The reason I hoped to know as we went is specifically so the results of the Golds training isn't a series of mystery boxes we open at the end.
Take the Armour of Lead spell. I'm of the opinion that it's very useful non-Battlemagic near-substitute for MMM they should learn. Yes, one or both of them might learn it, but it's (presumably) dependant on the dice. If we knew for sure they didn't learn it the first 'do as you see fit' turn, then perhaps we'd have voted to make sure the second turn. However without that prior knowledge, you might be making a redundant instruction, incentivising another 'unsupervised' action.
A one-line update to the character sheet would have done me. At least we'd have had the information to make that decision.
