On test 2, if the Bkool is using 200 watts as the power (based on your power meter), it should surely come up with a slower speed, not a faster one?! How can it think (wrongly) that it takes 220 watts to go 22.62mph (test 3), and yet on the same terrain, when it's being told you're doing "only" 200 watts, that would make you go 24.24mph (test 2)?
You think there is a difference how it connects auto vs manual? The second test was using auto where it automatically pics up the BePros. Perhaps I should retry that test using manual?
Ok, I just tried test 2 (200 BePro watts) with manual pairing, and I could not select BKool trainer. It was either Bkool or BePro.I, perhaps somewhat naively, think that in order to comply with the ant+fec standards bkool had to write the software and get it tested so it complied with the standard. That way, all things being equal, one turbo will perform much the same as another in an ant +fec environment eg. Zwift or trainer road. It took bkool a long time. My anecdotal experience is bkool pro is pretty accurate in zwift and i have said before my ftp there mirrors my ftp in Trainer road whilst in bsim it is 50-70w higher.
I also think that when i manual connect the differences or foibles we experience are much reduced or even non existant so i THINK a manual connect produces a more accurate outcome and the similarity with Andy's figure MAY reflect this...or not! So much is conjecture
Just done the Col de la Madeleine bit as well so hopefully am done now too. If not, I'll do the velodrome again this week.Cheers
Yes, apart from using Bkool trainer alone and using external power alone, apparently there's a third "hybrid" mode where they combine Bkool trainer and external power. Looks like that's the mode I should choose if I get in trouble in a velodrome sessionThis is really confusing (or is it just me?!)

I remember reading a post on Zwift saying that they can't use power from a power meter with a smart trainer like the Bkool pro, because the software gets confused with the two lots of power data being reported (or something like that). I wonder if that's what's happening in bkool in this "hybrid" mode?Yes, apart from using Bkool trainer alone and using external power alone, apparently there's a third "hybrid" mode where they combine Bkool trainer and external power.

The test I just did using the external power only, gives the same speed/power ratio as using bkool only: 21.7 mph/ 200 watt.This was also the same ratio as Bob and Andy registered, so it looks like they use the same equation for the none-hybrid modes.
I didn't try that, but since the Bkool trainer is not paired, I don't think so.
