The brain processes time better at lower frequencies. That's why bass is groovy and creates a rhythm. Practice timing on the top 2 strings if you are struggling.
Overlearning means repeat something you've mastered many times again to "lock in" your muscle memory. It also reduces interference from other similar chops.
When visual feedback is cut, brain activity in touch and sound processing increases due to neural plasticity. That builds muscle memory. Practice with an eye mask.
Stage 1 and 2 sleep (under 1 hour) reinforces what you've learnt. The brain mentally rehearses your finger patterns. So nap after practice to let your brain do its job.
There is "bilateral transfer of learning. Practicing with 1 hand gives performance gains to the other hand. So alternate between both hand's dexterity.
Your body adds groove and a sense of timing and it creates random idiosyncrasies by using that groove to adjust your hand movements.
Guitar playing is largely a finger "dexterity task. Knowing how your fingers and arms work can help you troubleshoot your movements. Visualize them to connect your mind and body while playing.
