I tested it once but the results were hard to catch (to many other variables, no stable ground do extract my research from). And no, I don't think it will build larger fleets. But you can set this in the setting.txt, too. But even if you have 99% of you ships in fleets, you need the ships do fill the fleets.

Have you tried changing this number to something else? If you have, have you noticed any difference in AI fleets? Forexample, is it using larger fleets in its attacks?
Gotta start doing some testing with this
