Getting skills past rank 5

[HammyTheSquirrel]

Hmm... I think the higher the rank, the lower the difference is compared to the previous rank. So I say you may have counted wrong for the rank five length and the rank eight length might be 22-23 seconds. And they are changed... trust me. Or else the rank would be cut off at 5.

I wan't to believe that this is true; however, the duration in the description of rank 5 full sail is 20 seconds. The duration described with rank 8 is also 20 seconds. And the duration of both ranks are 22 seconds exactly. If there was a change i would think that the description would change if anything.
