How many games you reckon are played in the 16 hours a day? Would it be close to the hay day of pinball?   I recall during a school holiday period not being run over by players to get off an acdc at a local arcade. I didn't see any coins on the glass waiting for me to get off, so I am having trouble getting a little perspective on this

Machines would be turned on 16hrs a day for 7 days a week no doubt if that's the opening hours. But played continuously for that duration?
.. Be taking that statement with a very large pinch of salt
