Would you really get airborne if you don't exceed your computed attitude?
Sure, ground effect increases your lift, so you can get airborne early. However, the final pitch attitude shouldn't be attained until you're already airborne. The wheels will come off around 6-8 degrees on a normal rotation and you'll continue to rotate. Rotate to 15 degrees on the runway in a -900, you'll have some paperwork.
