I’ve used sufferfest extensively in the past but the videos and plans are made for enduro’s. It’s not the same as sprint training where it’s give everything, rest and repeat. Rest periods are much longer. I’ve spoken to the guys at apex coaching who create the sufferfest plans and they agree that it’s not really the right thing for match sprint training.

Im just looking to set up some training workouts - the actual act of building these doesn’t take very long at all. I just need to work out the relative wattages between different gears, so if the instruction is power gear +4 for example, I know to set up x amount extra watts for that interval. I can then get these workouts prepared ahead of time and all I have to do in the morning is roll out of bed, load up the workout and ride.
