Most of the questions had to do with the "resistance curve" of the rollers and how it compared to the real world and their basis for saying each notch was about 50 watts (basically was determined by having rider do powertap run). There really isn't a precise formula / data out there like you might find for a Kurt Kinetic Road Machine.

I had one question re set up that he clarified (not sure what it was).

I should point out that I've owned the rollers for about 8 yrs with no issues.

I'll try riding mine at 60 rpm and report back later today. Worst that's gonna happen is I fall over.
