The only thing not clear to me is that flow increases with the length of drop (think negative head pressure), so it may be that a long drop drain would be somewhere between the gravity/low and medium numbers. Probably to a sump right under the tank the 2,100 gph number is a good guess.

I am flowing about 3500 GPH through 1 plus a little of another 1.5 inch drains. I have 2 full siphon drains with valves and 2 1.5 inch emergencies.

It could be what ever you want once you put a valve on it. (I think). I know I am not turning over 2100 gph, my Varios 4 pump is rated at only 1000 gph
