I'd venture that the samples at several thousand done at low morale are already of a sufficient size to guarantee the existence of its effect, though the exact magnitude of the effect may be somewhat more difficult to specify given that its effect varies with the ships' intrinsic level, luck stat, gun upgrade level and target evasion.

I can accept the argument that it is not documented with 'official' numbers as it indeed is not, but the tests are available... just that almost all of the data is in Japanese. If an official declaration is desired I suppose we can probably wait until the day Kadokawa officially documents the mechanic somewhere, though most new teitoku seem unaware the mechanic even exists.
