I doubt it lists those pressures for all conditions. Sure you're not leaving out the fact that it's talking about when you're riding 2-up or something?
I would use a car's owner's manual for tire pressure recommedations, but not a bike manufacturers. All sportbikes weigh within 50 lbs of each other these days, so why would one bike recommend 36/42 and another 32/36? It wouldn't make sense. I would pay more attention to the tire company's recommendations. Each tire is different, for example I think Pilot Powers recommend higher pressures than most brands.
And besides, like I said, I already run 40 or so for commuting, but I would never do that for a spirited run. Go to any track day, and regardless of whether you are just using street tires, they will tell you to lower the pressure to get more grip.
