So was thinking about this the other day and although I believe there to be way too many intangibles for the game to be beaten. Would be safe to assume that the closer we get to a "beatable NL game" that in theory a 5nl player would be able to confidently play at 500nl "as long as he has the bankroll to support it" without feeling the difference of player pools? For example if we put the stakes into tiers 5nl 10nl 25nl 100nl 200nl 500nl 1000nl, in the past the difference of skill level to move up in stakes were huge, but in present day the skill levels are much closer than the past with slight adjustments to ranges and aff. As we press on into the future the skill level should gradually reach an equilibrium, where the game at all stakes should be playing at the same skill level right? 

Random thoughts, ignore or flame if you will lol.
