I’ve been using TR for about three months now, training with a LeMond Revolution with Virtual Power indoors while recording my rides with a PowerTap G3 outdoors. A friend recently purchased an Assioma Uno so I offered to bring my trainer over for him to do a Step Test so that he would have an FTP estimate to start with.
During the test, I recorded the Assioma’s output on a laptop whilst also recording using Virtual Power on my phone (as I normally would at home) for comparison. Looking at the numbers, it seems Virtual Power reads consistently ~20 watts low across the board on my trainer. I know this is only one data point, and that it does not directly affect my training progress (outside of possibly having a TSS figure that is high for outdoor ride files), but I was hoping to be able to correct for the difference as it’s been bugging me since finding out. Is this even possible? Should I try adjusting the Virtual Power wheel size outside of the recommended 2070mm?
