Have a couple of questions / comments regarding the resistance on my Kickr:
Generally on uphill segments, my experience is that the resistance on my trainer relative to the grade is less than what I might experience through other Apps (e.g. Kinomap, Fulgaz) and what I might expect on comparable outdoor rides. For instance, there are segments that approach 10% grade on Zwift island that are considerably less difficult to pedal than 6% segments on Kinomap. Would be curious to see if other users have experience this as well.
At times, it does seem that the computer shows resistance slightly ahead of change in resistance felt on the trainer. For instance, if I am cresting a hill, Zwift may show a -% grade while the resistance on my trainer has not yet caught up.
