No. Find out IG means everything which your Char can find out.
To see if repairing effects the skill he has to do just this a long time and the chek his skills if the skill increases.
But your chars can't chek his skill, eh?
Alright, then it was just a misunderstanding of what was meant by 'in game'. I see a difference with in game and in character...
The player himself could find out while playing though. But then, Nitram spoiled anyway.
