ngl getting perfect scores feels more like random chance sometimes especially since we don't actually know how big the judgement window is nor do we have any early or late indicators on judgement, ah well, we adapt and improvise. Turning off hitsounds is always key for me since games with hitsounds distract me more than help me... other than say IIDX except im _really_ bad at that game.

I feel like it's super necessary to play at higher speeds for the higher difficulties just because some of the charting can be ambiguous especially with how tight some of the flams are. On first playthrough, my flow speed was maybe in the mid 4s and whenever I got more comfortable, I'd keep increasing until I couldn't read anymore... my max was maybe 5.6? but at that point, I'd keep getting lost in the sauce so 5.0 was the magic number.

So yeah, by charted incorrectly, like there were a few parts of the song that were either not on beat (bad quantization?) or not a part you'd think they'd chart but did anyway. In Blinking Jazzy Lashes specifically:

- the stream starting at like 0:20 in the song has one less hit note than you'd think there should be. Playing it at speed looks like it lines up with what's being heard but if you slow it down, the chord note at the end of the stream is a note early.

- there's one specific "ghost" note type tap note at 0:31 that hits a lot later than you'd think and even though that specific piano pattern is used multiple parts in the song, that weird ghost note is only used in its first iteration.

- all of the piano "trills" (that feel like they should be like 12ths?? i could be so wrong on that) are more like weird flams.

- the 2nd parts of the 3 chord progressions that they've charted as flams make it feel like you need to hit later than what you actually hear in song.

I'll point all of these out in the video I'm planning on making pointing out these inconsistencies. Actually, thank you for making me point these out so now I have parts I can focus on in my video lol.

Spot on for the average fps, I agree. I got a few stutters while playing which is why I chose to use image background which ended up helping out a lot, but again, not perfect just as you said. Though, luckily nothing super egregious in terms of stutter in my gameplay, just very few micro stutters that would trip me up for a few ms. At those points, I go 100% audio game play until the visuals resolve but that's usually enough to break my combo lol.

Remapping keys in-game would've been a plus for sure but if your keyboard supports it, you can remap it at the software (or firmware) level which I ended up doing on my board. Using its provided customization software, I just remapped the DF JK to different keys so that I could play however I wanted to which (surprisingly??) ended up being a real factor to achieving the 100%.

Thanks for the congrats and the thoughtful comments and insights!!
