But it looks like you are trainer is doing a thing where in ERG mode it pretty much just reports the set point as the power at any given moment. So if you're in ERG mode set to say, 200 w, it'll just report a constant 200 w. The alternative is it reports the watts you're actually doing, which will be oscillating around 200 w, but not simply a steady 200 w. Basically the difference between what you're supposed to do and what you're actually doing. It should average out to the same unless you're doing something weird or your trainer is broken, but they're fake numbers and I hate that and wish to eradicate them whenever I see them.
