I would love to know all about this, Tru!
Solidifying motor control patterns from short term to long term memory for skill execution
firstly short frequent practice sessions each week not 1 or 2 longer sessions
only train 1 skill at a time - don't try to multi task it.
use random variations of the same skill in the training session rather than big blocks of the same variant
rest between drills, fatigue both physical and mental hinder learning.
So for putting rather than 20 short putts, 20 medium putts 20 long putts etc. it could be arranged as series short, medium, long, short, medium, long etc or better still fully random short long, long, medium short medium, long, short etc.
the variation could also be the slope of the green rather than the length of the putt. so arranging all the balls at differing positions on the green before putting each one.
Mistakes are a learning experience
the science show that those who train in blocks appear to have better improvement within the training session but when a retention test weeks later and testing of the skill in a game situation the randomly trained people have far better skill retention and skill crossover into game situations.
