Hey guys I am in the middle of reading: 

"The Cambridge Handbook of Expertise and Expert Performace" K. Anders Ericsson et.al 

and 

"Practice Perfect..." Doug Lemov et.al 

to write an article and as a means of developing an optimal learning model whose focus rests on deliberate practice in poker.

What I need are players top 5 areas of PLO that they think makes them the most money. 

e.g. playing 3b pots, good pre-flop hand selection, 

I just need a base to work from.

If you could help that would be awesome
