Not really. If you launch 100 fleets and your target can stop 80 of them, 20 will land. If you launch 120 fleets instead, 40 will land, which is a 100% increase.

Considering that half of Ascendancy (the only alliance I know from the inside) barely plays, I'd consider it unlikely many people would be ok with getting up at night to launch on normal galaxy raids. Some might be ok with doing it a few times a round on special occasions (say, to roid Light), but very few would do it nightly.

By the argument in the first paragraph, it then becomes stupid to set up attacks for a time at which most people are unwilling to launch. To build on the example, if only 20 out of your 100 fleets can't or won't launch at 0:59, your landing rate is reduced to 0%. Similarly, if you set up an attack three times a day, you'll be able to launch fewer fleets each of those times than you would if you attacked once a day. Likely not down to a third of what you could launch once a day, but you only need to lose a few fleets to see your landing rate plummet.
