I think this comment on Reddit is the best take I've seen on the compensation:

tl;dr - For a 0.500 K1 player, the loss of crystals after the make good is about 400-500 in total.
I'd like to add, as others have pointed out, that the delay in the compensation did negatively affect some folks grinding for Executor. Also, when CG messes up hard like this, why are they so calculated in their response? Okay, it's probably EA shenanigans. But just throw some crystals out there on top of the calculated compensation to garner some good will, if EA will let you.
