Yes. I have similar problems using my wheel on, mag resistance trainer because the power curve for virtual power only goes up to 316w, but I still have half the cassette left to shift up gears. The first time I did full frontal my AC was higher than my NM and when I did Half is Easy, it was all easy because the intervals were barely above my MAP. I posted on the forum and was advised to bump up the figures by one of the coaches.
