Try waving a bat in real life as fast as you can wave your arm. If you can manage to do that you get +10 master-fap points.
I love all of these realism geeks who try to push it on the game and who simultaneously 
totally fail  to take realism into account.
Someone who
 practices waving the bat around like that is going to get 
really really  good at it.  thats why they make you 
practice sports and martial arts.  hence 
WPF points that exist in the game.  
proficiency levels.  It means your guy 
practiced it, and put time and effort into learning that particular skill.
of course 
YOU cant do it.  you dont go outside and wave the bat around for a few hours a day to get better at it.  dont try comparing yourself to an RPG character or a real life warrior who supposedly DID spend his time doing just those excercises
