I understand what he's saying but I'm wondering if he just made up that number for the interview or how he calculated that number.

If all your early hands really only account for 20% of your ROI then AA-TT and AK probably account for such a huge portion of that 20% that all other hands probably don't even matter. Not that I play anything else besides some smaller pairs but maybe even those chips should be saved...
