This month (not so sure about previous one, but probably also), I found that I have more 1st places in zwift-races than before + I feel that race is definitely easier for me. Success? - I do not think so. I spent a lot of time comparing numbers from my neo vs SRM - numbers were not totally the same, but dispersion was not so huge + all this numbers were ~ near my expectations.
I checked my SRM, checked my neo - I compared in another programs and application - recalibrated/checked my SRM. When I keep constant power - numbers ~ near like I want, but in race I do small sprints all the time - and I found that it helped me a lot.
Today I decided to record race on all devices I have: neo + SRM on zwift-pc, android, wahoo-bolt, srm-head. But I suppose that the only comparison from zwift-pc and wahoo-bolt would be enough to show that zwift is totally wrong in result power-curve.
Please find attached image, sorry for the quality - it is necessary to zoom-in to see the numbers, but zwift has is significantly higher numbers than wahoo.
Unfortunately, I am totally disappointment with zwift - looks like I spend last months training on a wrong power number. And I disappointment twice - because all the 3d and GUI is not so important for me like the correctness of the number. And the company with a lot of developers and managers cannot calculate and check just one number - it would not be the problem if it would be number of “drops”, but the number is very important for all results of all races which happens
