The problem with these numbers is we don't know what they actually mean.
From what I see the 2011 numbers do show a substantial increase in flying by the average pilot, but throw in S/L, vacation and other items such as DH pay and the numbers seem low.
What is need is the distribution, and the mode of the fleets to get a better picture of reality.
This is the problem when people start throw numbers and they get used indiscriminately.
