This is basically what the Wyoming Rule does. It sets the ratio in the lowest population State, currently Wyoming, as the ratio for everywhere. Wyoming currently has 500,000 people and 1 Representative. That means the HoR would expand to something like 580 Seats.
We could change the math, and the name, to the “1929 Rule” and set the ratio 280,000 to 1. I’m actually fine with an HoR that has 1,200 people in it but either way the Re-Apportionment Act of 1929 needs changed and the HoR needs expanded.
