Oil Flow.

[allencr]

sufficient overflow capacity.
The baffle system in question is typical, but I have built it myself.
final issue was the mini-sump might overflow
have sufficient drainback to the main side sumps.
the oil from the outer sump will be constanly forced in and out of the centre sump- time to cool in the outer sump before it flows back into the mini-sump
the pump is continuously pulling oil from the mini-sump

I think you are over thinking the simplicity of this and putting too much into it. I thought that this was some sort of extra oil tank/sump that was being plumbed in to increase oil capacity & positive delivery or some such. If it's just baffling, I think you'd find that the same type of horizontal plates that many manufacturers use, will prevent the oil from climbing the walls works really well.
Does yours need to be biased for a circle track?

The capacity is the total flow out of the pump. The actual flow through the engine would be that less the (unknown and variable) quantity that is passed straight back to the sump through the relief valve
