OK thanks. It was driving me insane looking at that chart. They claim 7% at 75kg which according to their own graph is wrong. That's about where I'd be at with bike plus rider so it looks like anything over 4% is out the window. Which is totally weak. I'm surprised it's so highly recommended. That is the farthest thing from realistic for even the slightest hilly route. Oh well, the idea of a sub $400 trainer that can actually simulate real roads is still not available. Now it's a matter of do I want to push up above $500 for one that will. Probably just stick to my dumb trainer.

BTW, where did you get your Genius for 550? Even on those German sites, the best I can find is just over 600
