Over the RPM range.
And in particular (see below): How does it respond to a partly closed
thermostat? I've never seen an answer to that.

Or rather: What is required in terms of coolant flow to properly cool the
engine at the max bhp. point? Or at 60 mph steady speed, for instance?
What would the corresponding electric pump power requirement be?

With modern power control eletronics, that would be quite trivial. And would
completely eliminate the need for a thermostat.
