For 3rd slot:  Sqrt(46)*10 + 25.5 = 93.3 FP

4th:   Sqrt(12)*10 + 25.5 = 60.1 FP

Close enough for general purpose, you can try the  calculator  to speed things up.

Dogfight shotdown is proportional to slot size (and air control state) so you're right about bigger slots suffering more. With aircraft proficiency in play though, it is usually more efficient to put the fighters on smaller slots on multiple carriers and free up the big slots for bombers.
