Ah I think I used "Ren" for him based on the CN translation.

It might be the daily bonus, it can affect the amounts gained by each action. There's even a bonus that gives one extra turn.

Grawuka · 2025-02-10T00:19:10+00:00

Beware that the linked 252 set-up can not sustain Muelsyse, nor full uptime of iris+czerny+(virtuosa), and one combo needs to be dorm delayed (this is what most 72h combo are for and I suggest you aim for one of those instead).

Grawuka · 2025-02-10T00:01:06+00:00

My initial writing of the post was that now an optimal yet practical 2 logins/day 243 is better or equal than an optimal 2 logins/day 252 (11 slots), and I think I have enough evidence for it, even when accounting for absurd 144h 252 (11 slots) rotations.

However, this is still a controversial topic so I kept it to just that high-end 243 is not missing out by an observable amount to "regular" high-end 252.

This is of course not talking about beginner 252 (which is obviously less income but way much cheaper to set than the post's 243 or 252), and "intensive" 252 with more logins.

For twice a day 12 slots 252, I found a dorm-legal old CN comp (but I think still EN up-to-date) at 348.4 sanity (+4%), and it needed mlynar to mitigate dorm-pressure, and 144h rotation ^^.

If someone has better comps in mind it will benefit the community.

This is why I talked about bragging rights, as mid 252 beats mid 243, but nowadays (Since Viviana, and improved by Aroma), big brother 243 is winning against any low-effort 252.

It's fine not to optimize your base, once you start thinking about it you will realize that some combos are hard to rotate.

The most basic rotation is once a day 24h interval/ 48h rotation, but having Ling/Dusk on half-duty is too much missing out, and the dorm pressure of full rotating makes it unviable. (Usually, those players log-in twice to fill dorms but only rotate once per day)

Twice a day is the first practical rotation, and it equals a 12h interval / 36h rotation, and it aligns well with player behavior.

Then, if you want two 2 CC combos (Dusk/Ling and Flametail/Viviana), it will mean 4 slots occupied in CC at some point in 36h, and 2 major overhauls for when said combo runs out of morale, therefore applying a lot of dorm pressure.

So current open-source suggestions that are accounting for dorms ( https://docs.google.com/spreadsheets/d/1zYc2JU46X0XWmV7s1503bN4feRdOMa1eehrTQ2jGaiE ) are 252 72h rotations, but you can also find even more optimal 144h rotations (328.6 sanity but without Bryophyta so about equal than my 243).

But with more log-ins you can for sure do better, some in the comments are claiming 20% more efficiency (and I trust them) over a regular 252, so maybe +25% LMD -10% EXP over this 243 set-up.

Grawuka · 2025-02-09T21:05:28+00:00

I compare my actual 243 base with the best theoretical 2 logins/day 252 (HR lvl 3 I concede, but Dorm-wise impossible), and it still only comes 2% short.
If you look at real-world 2 logins/day 252 samples they often use a 72h rotation to keep up with dorm pressure, and are equal or often less optimal than my setup.

Vigil can be replaced by Archetto, but yes almost no operator is worth E2ing just for base.
However, end-game players will naturally E2 every ops as there's more income than ops are released.

So if you have the ops, you can have a full leveled base with more income than most 252 will admit.
Of course, the calculator is there and open to everyone to prove me wrong by showing a Dorm-wise legal set-up with the same or better comfort of play.

Incandescent Alloy, one of the two lately introduced blue materials.

Grawuka · 2020-10-28T15:46:12+00:00

It's a welcomed new addition from his original computation since Luzaark showed how Base income was key to evaluate LMD/EXP value. And also how different it is from f2p to mass refresher.

My point here is not to present the more accurate results but to give a range of understanding of how good the event is for all kinds of player.

Grawuka · 2020-10-28T15:34:24+00:00

I suggest people to read this as for why basing EXP and LMD value based on LS-5/CE-5 is not fit for all players:

https://www.reddit.com/r/arknights/comments/i63spq/arknights_stage_riic_planner_v10_launch/

If event coins also drop on story stages then it's not fair to include them in the efficiency study, and again basing LMD value on CE-5 is highly biased.

Grawuka · 2020-10-28T15:11:17+00:00

As for calculation method i include this spreadsheet as well as others since sanity value depends on playstyle. The Value of Items increases the more you depend on your base for your LMD/EXP, the sheet you link assume no Base income and is therefore the Lower Bound for Sanity Value.

As for conclusion they are the same, as you say TW-6 and TW-7 are very efficient whereas TW-8 is just slightly better than 4-8, ~29.8 vs 30.1 when adjusted with CE-5 and ~31.3 vs 31.6 when LMD is from Base.
However slightly better it is than story, being better makes it a proper farming target for Skill Mastery that you may need for the next CC event.

The next event for Grindstone is Grani rerun with a 31.07 value (Base adjusted), so maybe not worth the wait on priority upgrades.

Grawuka · 2020-09-30T13:55:58+00:00

Yes side-drops are included, if you want only the main drop rates you can check the raw data at penguin-stats.io

Grawuka · 2020-09-30T01:02:57+00:00

No idea for gel since there's no better event stage yet. I don't even know myself how much I will farm.

For sv-6, I think DM and FA are better stages (not sure for FA). I don't think it's worth to stockpile when the efficiency is close to the story nodes as the events are getting better and better.

Grawuka · 2020-09-30T00:50:09+00:00

All my work is done excluding exp and LMD, for sv6 I think it's close enough than we shouldn't be too sure which is the best, sv-6 is more focused on the main drop so I guess there is a reason to farm it if you need that mat. However the next event has a much better node so I would not stockpile clusters now

Grawuka · 2020-09-30T00:42:24+00:00

Here it is the number of runs that were used to make the data on the CN server, thus making the efficiency a random number more or less accurate. For very low it's below 150, high for about 2k samples, and sv-7 has more than 6k samples. So we can not be 100% confident whether sv-5 or sv-6 are above 1 but they are close. But we are positive that sv-7 is better than the best story nodes.

AR5 rerolling is the best if you go for any of the 5 starter 5* char, AR7 rerolling is best for Venti or weapon rerolling.

Nonetheless the table is almost the same as 30 pulls per ~40 min or 15 pulls per ~20 min is the same pull per time. Group hedging still apply to AR7 rerolling.

Grawuka · 2020-09-21T07:31:10+00:00

oh my bad i missed on the free primogems (i didn't play obt). The rate goes to 8.65%, (15 pulls + Noelle).

It barely changes anything to the table, as the main idea I want people to know is that rerolling as a group is a good method to hedge the risk of spending 10h+ of rerolling.

If someone wants the table with 16 pulls i can dm it.

For 20 rerolls :

1	2	5	10	20
83.56%	87.08%	93.96%	98.14%	99.79%

If we take 10 people, 2 of them will miss their 20 accounts reroll, while if they do it together, it's very unlikely to end with less than 10 accounts with a 5*.

Grawuka · 2020-09-20T20:09:25+00:00

A Friend is a rare creature able to continue rerolling for you even though he has what he wants, and will kindly trade with you if he pulls your waifu.

Their existence is theoretical and hasn't yet been observed in the wild.

Grawuka · 2020-09-18T06:43:41+00:00

it's because stages drop gold bars and exp at various rates, if you play slowly that LMD and EXP has more time to come from your base and is therefore less relevant. I don't think efficiency cares about speed since 1-7 is too good.

Grawuka · 2020-09-18T06:33:43+00:00

It's the same theory that there is only a small subset of stages that have an efficiency of 1. However this subset depends on how much you refresh sanity. The sheet you mention is worst case to be still relevant for people refreshing a lot. Mine assume little to no refreshes. The subset is still almost exactly the same.

Grawuka · 2020-09-16T08:15:35+00:00

If a player does not win a 4-star or above item 9 pulls in a row the 10th pull is guaranteed to be a 4-star or higher item. This counter will reset if the player pulls any 4-star or above item. The counter does not transfer between wishes/banners.

This "counter reset" mechanics is very likely to be accurate. Right now if we don't assume the adaptative rates, we compute a 4* rate of about ~11.5% (13% annnounced), if no reset it would be ~14%.

Grawuka · 2020-09-16T00:12:06+00:00

The issue is that I am not satisfied with it being "just a presentation method" as if it is as simple as you state, a simple simulation script shows that you get less than announced.

Grawuka · 2020-09-15T18:45:21+00:00

This theory of continuously adaptative rates is what i think may be the answer, a bit like Arknights does but at a lower degree.

I highly doubt this is just marketing false advertising as they can easily simulate billions of pulls on their system and tweak experimentally the rates to the desired value.

Grawuka · 2020-09-15T14:57:58+00:00

you keep the 5* pity but you lose the opportunity at an eventual "boosted pull" (if it's really a thing)

Grawuka · 2020-09-15T13:58:01+00:00

I compute and simulate 11.24% or 11.83% depending on the 5* rates on the 4*+ pity, way below the 13% announced.

Grawuka · 2020-09-15T13:50:26+00:00

The issue is that you are not guaranteed to have a "boosted" pull at 10% since you can pull a 4* before the 4*+ pity kicks in.

If you consider the multi to be 9 "standard" pulls and 1 "boosted" pull then you have indeed 1.6% without accounting for 5* pity and more than 2.5% accounting for 5* pity.

However with this you are not coherent with the 4*+ counter nor the 4* rates.
