Description

This data field display your W' Balance (%) live during a ride. This value is displayed into the GoldenCheetah software, and well described on the video here: http://vimeo.com/100599100 </p><p></p><p>Check all the details on my blog: https://www.trinakan.com/wp/2016/04/02/everything-about-my-w-bal-w-prime-balance-connect-iq-app/</p><p></p><p>It needs 3 parameters: your Wprime value (in joules) and your Critical Power (CP) in watts. You can choose also the formula used to compute the data (starting with version 1.2). Use GoldenCheetah to help you find the correct values if you don't know them. Of course, a compatible powermeter is required.</p>

Very cool being able to take advanced statistics I normally only look at in GoldenCheetah out on the road.

I love the idea of using this for races. I have an issue with how it works on my 520 though. The values were not going down fast enough. When I compared the Golden Cheetah file, I was down to like 5.4 Kj remaining after a hard climb, where during the ride it displayed like high teens to 20 kj left. I thought I was being weak. I think I loaded the CP and W' data points accurately.

Hi, Thanks for the feedback. Are you sure you are using the same algorithm in the data field and GC (differential or integral) ? This may be the explaination. Cheers.

Fonctionne parfaitement et permet de bien se gérer. Au début je le regardais après coup pour confirmer mes impressions et parfois on s'aperçoit qu'on peut en remettre un peu. Attention il faut que ses paramètres soit parfaitement configurer dans GC (que la FTP soit juste est primordial) pour avoir des enfants infos au plus près de la réalité. Good job :-)

après essai en bosse 55km 900m de deniv pas mal du tout je me fixe d arrive a 90% au pied des bosses alors que j étais a 45% du réservoir 10mn avant c est assez bluffant quand on sait bien ce servir du capteur

Work for many devices, have setup formula, full compatible with GoldenCheetah

same comments as another person. Seems like there is a math problem: The calculation in the app deviates from the Golden Cheetah program. The W' expended is less than calculated by GC, and the recharge of W' is to slow.

Absolutely perfect. This is why I purchased the Edge 520. Clear display of remaining W'Bal % in a font as big as any other data field. Thank you.

No issues found installing or configuring v1.1 Still pending to take the Garmin out for a spin to see it in action.

Sorry, no statistics available yet.
