Thanks guys for the replies. I will be using TR over the coming year so it’s just a question I guess which PM source to use, the Quarq, which is obviously my outdoor PM too, or the Neo. I never noticed such a discrepancy between the Neo and Q before but now that I think of it I did not calibrate the Q before the test today. Could this account for the 20/30 watts?
Either way I think I will use the Neo’s power readings for now, repeatability and consistency as JoeX says.
Acavell I had to estimate my FTP so I guessed 215. My understanding with the new ramp test is that even if your estimate is on the low side the nature of the test you will still get a decent estimate of your new FTP.
