I wonder what the correct ideal weight and balance is on a horse drawn plow? Any idea what the ground contact psi is per hoof? Talk about compaction!

Depends what you use for a plough horse.
Generic all purpose "Compact utility" farm horse might be as low as 900 lbs,
Ahh, but then there are the draft ponies, which could be even lighter.
Up to Shires, Percherons, Belgians, Clydes, etc; any of which could be well over a metric tonne EACH - and I've heard of 9 horse plough hitches still in use on Amish farms in PA.
60% on the fore, 40% on the hind, but that is static; when they get their hind legs under their hind ends the front maybe gets a bit light.
Figure it comes down on an area about the size of... again a range, anything from a salad plate to a dinner plate, (maybe serving platter?). At least it is compaction in a few points, not a couple of 18 inch(or more) wide strips.
I'm sure the plows were developed to match various sizes and weights of horses, the horses were probably not loaded with ballast just to add traction, so I'd guess they were well matched for power, weight & implement.
{Yeah, I'm convinced that the implements were designed to match the horses - fairly sure anyway}
