Post ride Analysis

[benlane]

Hi
i have had my ibike pro for around 18 months now. As the race season is a month old for me I decided to do another 20 min FTP test this afternoon. I notice on my day to day usage that pre and post repair analysis with the software sees quite a fluctuation in power for the ride. Anyhow, as the FTP figure is one that I will use to guage my training on before I checked the wind and tilt and slope variances with the software my reading was 263 watts. With then analysis this rose to 357 watts.
Knocking 5% off this figure as per Hunter Allan's protocol suggests an FTP of 340 watts.

Does anyone else see this level of post ride correction?

Hi Ben,

That is a large jump in the post-processing. Send the file to me and I would be happy to look into it: travispape at yahoo
