Can you show me data from a TEC manufacturer that says this?
The clamping pressure recommendations are to ensure good thermal contact between the TEC and the hot and cold plates. It has no significant correlation with the current draw.

This is (almost) total nonsense. The current will continue going up as the voltage goes up. It's not going to stop going up at some magical point of optimal pelt operation. Given a beefy enough supply, it will continue going up until something dies.
I certainly would agree that checking the CPU temperature over a wide range of pelt voltages would be a good idea. (Need to give the system time to stabilize at each voltage setting though.) Not many people are going to have the supply to be able to do that testing though.
