Yes, I see your point, and do recall since I was collecting the data. I should re-phrase my statement. Interceptors during wave 3 Regionals accounted for around 11% of points spent, with generics comprising slightly more than half of it, and they generally pulled their weight well, showing up in the top of a few tournaments. But it was a one-off in the entire history of the meta so far, and the common factor in all of those builds was either squad leader, or stealth device and very particular formation flying. I don't think any of them relied very much on the boost action. Now that we have some very powerful turreted ships in wave 4, let alone wave 5, it is very easy for the Alphas to get picked off.
The real metric is determining how much more efficient you think the ship can be by getting a boost action and getting green 2's. The magic number for the Alpha Squadron Pilot is 122%. You need to hit that target in order to pay back the 2 points you paid over its jousting value.
