On the deck gun firing rate... believe the fire rate for the 88 milimeter or 8.8 cm, was 14-15 rounds per minute... which would give a fire rate of about 1 shot, per every 4 seconds... on the 105 milimeter or 10.5 cm deck gun, believe it was about 11-12 per minute, which would be hmm... about 5-6 seconds rate per round.
Now, given that at that rate... coupled with the accuracy or lack thereof, on gun fire... would likely burn through the ammo stores, rather quickly.
What I did, was to set the rate of fire for the 88, to 1 every 6 seconds & on the 105, to a rate of 1 per every 10.
But... that's just what I set it to. Could very well, make it 8 on the 88 & 12 on the 105.
With those rates, it makes sense, when you consider that the weight of the shells & the 88 being a tad lighter in the loafers, as it were, in comparison to the 105's weight... so it makes sense that the rate of fire, would reflect that.
Meaning that the 88 would be a bit faster to reload & fire compared to the fire rate on the 105.
Hope this info helps...
