Must admit I don't have a lot of info on training but,
it would be probably possible to contact the Ufficio Storico to get more precise info.
Thanks a bunch TOS - I will keep hunting!!
The first event set that lead me to think about training was reading about the problem of some Italian submarines leaking poisonous methyl chloride gas, thus impedding their operational performance.
(Stern, R., "Destroyer Battles", Naval Institute Press, p121)
Was this issue known before the war started? If not, then that would point to a training realism issue - if it was known then that would point to severe negligence.
But it would seem logical that a comprehensive understanding of the capabilities of a Navy should include data regarding individual, ship and unit training.
Combining a study of the manpower readiness side, with the equipment and the logisitics would then tell the whole story.
