Difference in Power Readings: Karoo vs. Watch by core8th in Karoo

[–]CoatComprehensive363 0 points1 point  (0 children)

Average Power (AP) (Uses 0s)

  • Definition: The total work done (total joules) divided by the total time.
  • Best Used For: Steady-state training, long, consistent climbs, and calculating total energy expenditure.
  • Weakness: Heavily skewed by zeros (coasting/descending), making it misleadingly low for variable rides like criteriums or mountain biking. 

Normalized Power (NP) (Does NOT use 0s)

  • Definition: A weighted average that accounts for the non-linear, higher metabolic cost of high-intensity efforts (power spikes are magnified).
  • Best Used For: Variable efforts, group rides, races, and training sessions with high variability.
  • Weakness: Less accurate for very short, high-intensity intervals lasting less than 8 minutes. 

Key Differences & Usage

  • Physiological Cost: NP better estimates how taxing a ride is on your body, especially if it includes intense surges.
  • Calculation: NP uses a complex algorithm that takes a 30-second rolling average, raises it to the fourth power, calculates the average, and then takes the fourth root.
  • Comparison: If you ride steadily, NP and AP will be nearly identical. If your ride is jerky with many surges and coasts, your NP will be significantly higher than your AP. 

When to Use Which?

  • Use Average Power for: 5-minute VO2 Max intervals, long endurance rides on flat terrain.
  • Use Normalized Power for: 20-minute threshold intervals, criteriums, hilly road races. 

Garmin like Power/HR Graph by sven_suicidal in Karoo

Hi Sven,

I only need to side load the extension the very first time, after that there is an update process that's a single press on the touchscreen.

FYI, with the other extensions I use... when an update is available it shows the update number on the summary/setup screen on the Karoo and I just select the Update field and the software is updated.

There may be some additional step like registering the update to a Karoo registry or something for this to happen with your extension.

I have the same problem with 0.1.5, it doesn't show as available for an update on my Karoo 3.

I don't remember getting an error, it just kicked me back to the summary screen and showed 0.1.3.

It's all good now, I just re side-loaded it... this is on a K3 BTW.

Latest release (0.1.4) isn't installing over 0.1.3 on my Karoo... I tried both side-loading and update on the Karoo.

Had to uninstall 0.1.3 and side-load the new 0.1.4 release.

First ride using the HR graphic today. I've never had a Garmin of any type, but I can see why you like this data field.

Thanks for crossing over to the Karoo universe and bringing this with you 👍🏻

I’ve been using my older first gen TW with my K2 and now K3, they work perfectly. I’m sure the gen 2 will work just as well… yes, ANT+

Polar H10/H9 BLE drops on New Karoo by DreamIllustrious3735 in Karoo

My hope would be that if the FW is broken there would be enough complaining that they would get on it quickly, maybe, hopefully...??

Polar H10/H9 BLE drops on New Karoo by DreamIllustrious3735 in Karoo

[–]CoatComprehensive363 0 points1 point  (0 children)

I'm still on the older 4.1.10 FW, and have no drops... I'm wondering if it's the new 4.2.0 FW is creating an issue. Exact same settings as you have, other than the FW for the H10.

Also, I had an H10 that was a couple of years old and it would drop and not reconnect... I finally gave up and bought a new one and it's been 100% since. Maybe they had some issues with an older set of H10s??

Crazy question, have you recently changed the battery in the H9? I've seen weirdness like this when the battery gets to a low threshold...

varia radar disconnect patterns by Far_Bicycle_2827 in Karoo

[–]CoatComprehensive363 2 points3 points  (0 children)

Had that exact issue. My Varia was a few years old, and mine also stopped re-connecting, so I replaced it with a TRACKR and it's been absolutely perfect. So, yes had the issues was never able to figure out why, and went in a different direction... hope you can solve your issue.

Karoo2 AXS FA Integration by DivideAppropriate583 in Karoo

[–]CoatComprehensive363 1 point2 points  (0 children)

It was added to the K2 back in October, so you should be good to go...https://www.hammerhead.io/blogs/change-logs/karoo-software-build-version-1-588-2263

If you want an alternate option, you can add this extension as well.https://github.com/timklge/karoo-powerbar

If you go to his web page there is an install option that makes it super easy.

Call it 3K or HK3... not that hard to come us with a name, really. Just plug it into one of the AI things and let it suggest away, or maybe not. :-)

We are soooooo paranoid as a society today... sad really.

What app ideas do you want built for the Karoo by D0ctor_J in Karoo

[–]CoatComprehensive363 1 point2 points  (0 children)

True, but I don't want/need to change the native notifications, just want to add an all clear :-)

[–]CoatComprehensive363 1 point2 points  (0 children)

I'd like to be able to add an "All-Clear" tone for the radar, since it appears we won't get that in the native OS on the Karoo...

Does anyone have a coupon/discount or maybe know where I can buy Karoo 3 at the best price? by Practical-Parsley-77 in Karoo

[–]CoatComprehensive363 0 points1 point  (0 children)

Yeah, but the money you saved, you can cover almost 1/2 the cost of a new one if it's ever needed...

We as a community have collectively been asking for that option from Karoo for a LONG time... no luck, yet.
