Effective skill 27 is a level that gifted semi-realistic humans can reach, with the right talents and careful collection of conditional bonuses. 38 is the province of demi-gods.

Even the 1200 point PCs in my 'Traveller' game haven't got to that point yet. I think their highest skill is 32 or 34. That was the point where it finally dawned on the player that their marginal returns on skill increases was getting pretty low. In my opinion that point had been reached in the mid-20s.
