I have to replace the shoes on my rear brakes about 10 times more often than my front brakes.

That just means that you brake with your rear the most. I'm talking about maximizing braking potential.

I've been riding motorcycles for decades and it's drilled into you to practice panic stops regularly, which habituates the transition from 50:50 braking to 90+% front brake. I don't think many cyclists do this exercise, but they'd probably benefit from it.
