And I don't know if you have heard, but QuickyBaby was showing off a way to get a 100% retrained crew without using gold.
If you have a crew member with at least 1 skill at around 50%, just drop the skill before retraining them, an then when they are retrained, some of the xp from the skill will go to making them 100% again.
