Yes, it will recharge faster than non upgraded base cannon. There is advanced tactic that upgrade cat cannon recharge but not upgrade the cat cannon power at all to achieve rapid-fire cannon.

The calculation goes like this (if I remember correctly): Cat cannon base stats: 100 damage, 60 seconds reload (100 DPM) Each upgrade for power: +100 damage, + 1 second reload Each upgrade reload: -50 damage, - 2 seconds reload

So leys say both power and reload upgraded to max 20+10, you will end up with 3100 damage and 30 seconds reload (6200 DPM)

But without upgrading the cat cannon power at all, you would achieve 100 damage and capped 1 second reload by animation (DPM is around 4000 to 5600 depending on stage width). But with 100% knockback of beam, this will keep enemy out of the bay.
