i completely agree, i was just using the stats presented by the other poster for consistency. I'd argue its more 60/40 in my experience but thats subjective and anecdotal.I’m arguing that while often it’s true that classroom/ range learning under trainers can be important , it’s not as black and white as assuming that 20 percent of knowledge/ skill (to get to ‘objective proficiency) available is left on the table if I skip it.
One questions for you, if you are taught the 4 firearms safety rule and follow them without fail, how would you ever holster a gun?
