specifically about this part:

So, for example, you'll know that a 60/100 power rating is actually above the league average (which is always 50 in the 1-100 rating scale) - by one standard deviation, to be exact (for you math heads).

So, does that mean a 70 is 2 SD's above, an 80 3 SD's, a 90 4, etc?
