Where EVERYTHING must change based on your opponent, meta, matchup and strategy. It is not based on perfection but more on an extremely diverse set of skills that can be swapped between at will. As such focused practice shouldn't be praticing your golf swing over and over again

It should have far more diverse stuff and range of practice for maximum gain. As a pro the best practice is an opponent doing the same build 20 times vs you so you can perfect your reaction but also so you can experience and understand all the weird paths the game can go down

Final thought: you look for systems and repetition to create consistent practice and order in the chaos. You hunt for set plays and reactions and automation - but it all floats within the most ultimately flexible game where mental flexibility and adaptation is always number 1

The modern training approach for comparable sports (e.g., basketball) emphasizes on automation of mechanical skills that doesn't require deliberate "attention". This is based on the long standing finding that human has limited cognitive capacity. 1/

When players practice dribbling, they are required to do other activities at the same time that require attention to situation and decision making (e.g., press the button that light up - there are multiple buttons). 2/

This makes dribbling a low attention activity in game, so players can pay attention to other stuff on the court. This can be thought of as not missing worker and supply building production when you are dealing with specific harassment that requires adaptive actions. 3/

So a "diverse vs. specific" perspective may not be the best way to think about SC2 practice as of current knowledge. 4/

This is effectively the same way musicians are taught: develop control of low level skills (notes, rhythms, dynamics) so that you are able to focus on broader ideas (phrasing, musical direction, atmosphere, etc. in this case). I think this is a very broadly applicable strategy.
