I have no idea if this is helpful or not. I first started out with a Kurt Kinetic dumb trainer and did the 8 min FTP test. One year later I upgraded to a smart trainer and did another 8 min test and was within 5 watts of the Kurt Kinetic. I may be way off here, but I think you would be better served to do the 8 min or 20 FTP test as these are just all out efforts and will not require you to gauge your effort every minute.
