Why is adjusting drum brakes so much trial and error?

Drum brake adjustment often feels like a guessing game because putting the cover on, spinning the wheel, and taking it back off makes it hard to get a balanced feel between both sides. When one side binds up with play in the shoes even when fully bottomed out, it stops you from achieving a free-spinning wheel and a solid brake pedal without endless repetition.

“Only on this side the drum won't spin freely and is being held up by the new shoes, drum goes on nicely and fully seats. Adjustment screw is fully bottomed out. The only difference we are noticing is that the shoe has play on this side, while it is tighter on the right.”source ↗

“How do i know I’ve adjusted the shoes too much and in this case do I just need to loosen the handbrake cable from inside the cabin or back off on the drums?”source ↗
