Number of pilots in TRACOM when this screenshot was taken was:
IJA - 151
IJN - 429 (!)
As can be seen, adding a substantial number of pilots to TRACOM leads to large increases to IJN pilot skills, allowing unnamed pilots to be drawn from the replacement pool with EXP much higher than they should have. Range I have observed from drawing unnamed pilots was from 67 EXP down to 48 EXP.
Interestingly, IJA pilots do not seem to be affected by this large increase. However, it is possible that this is a reflection of smaller numbers of IJA pilots on TRACOM duty.
While it takes a fairly substantial effort on the part of a player to amass this number of pilots in TRACOM, it does pose the potential to be game-breaking in that large numbers of pilots can be churned out with high EXP values, and potentially (if sufficient pilots are added to TRACOM) to create a positive feedback loop by enabling pilots to be drawn from the replacement pool with EXP greater than 81, and then immediately be sent back into the pool to provide a further boost.
