i.e. of the average cross sectional print of the entire block, how much is copper and how much is liquid.... a good ratio I found to be about 60% liquid and 40% copper. obviously the granularity of the divisions will have an astronomical effect on efficiency as well.

Thank you. So we have
1- flow restriction vs pressure and turbulence
2- flow path length vs backpressure
3- base plate thickness vs heat spreading / resistance / capacity
4- channel pathway for optimal cooling (crossflow ?) vs flow path length and restriction
5- channel shape vs liquid properties of water (or wiper fluid)
To which I'm going to add point #6 (your point).
6-Cross sectional material print
(It touches on #1, but that's ok)
For baseplate (#3), i found something in the OC forum (I'll get a link later) that indicates that 300 gph effective flow reduces the difference between Alu and Cu to 1 degree of effective cooling. It was preliminary, but is worthy of mention. It's going to be critical, because it will also link to the flow rate.
