i kept them in the cups for about 5 or 6 weeks from the look of the roots at that time if i had left them in the cups for another 2 weeks they would be pretty root bound.

you can always just wait till the soil is dry enough and just turn it upside down and pull the cup off gently and check the roots to see how the roots look and if its ready to transplant.
