At first, let's look at the birthday distribution of pilots who were active in this period:
There clearly are new pilots in Goonwaffe, 104 out of 1010 was born in the latest half year. Still, the vast majority of pilots are old, the average birthday is 2010-06-16. It's interesting that large number of new pilots started to appear in 2013 and this trend seems steady. Let's look at their performance against non-blues, after placing them into 5 age groups, divided by the red lines. If N pilots killed a ship, they all got 1/N kill and Value/N ISK:
So far it doesn't look bad. They fly cheaper ships than average and have less kills, but that's expected. But instead of averages, let's look at the performance of the individual newbies (every bar is one of the 104 newbies):
PS: I guess some of them had their first "fun frigate fight" is this battle.
