I don't have a Power meter. The only power measurements I have are from TrainerRoad with it's calibration for the KK Road Machine trainer.

A month ago I did my first 8 minute FTP test which gave me a measure of a measly 166 (2.46 Watts/Kg at 148lbs)
I've been training regularly for the past 4 weeks and have gotten to the point where I actually enjoy riding on the trainer.

This morning I did another 8 minute FTP test which gave me a measure of 183 (2.74 Watts/Kg at 147lbs) which was a nice surprise.

Is a 10% increase in 4 weeks normal enough that I can expect similar gains for another couple months? I was quite well rested this morning and it is quite possible that I was not rested the first time I did the FTP test

What is the average FTP of people who race at a Cat 5 level? I understand there is a lot more to racing than just power. Road/crowd/group dynamics and strategy aside, I'm just looking for a power level comparison.

How does the Power calculation on TrainerRoad compare to actual power on the road?

Thanks, V
