News flash: we all do. At least, all of the experienced players on this site know advanced techniques and mostly play in a niche which we have modified our play for. An inexperienced player doesn't have $800 from his bankroll to spare for counting lessons, rather he needs to read a couple of $20 books and get out there and earn his stripes. On this site we've watched a young man quickly go from a rookie frustrated because "this counting stuff is hard" to a successful journeyman counter, just with some study, experience, and asking the right questions of the right people.
Furthermore, as far as straight counting goes, being a great one is sort of like being a great cashier or barista. There isn't a whole lot of difference between a great one and an ordinary one, in units of dollars. Sure, I use level 2 and 3 counts but it will be years of play before there is a mathematically significant difference between my play and that of a guy who uses Rookie KO. Therefore for me to represent myself as significantly better at counting than the rookie would demonstrate that either I don't know what I'm talking about, or I'm being dishonest. If I were also attempting to extract $800 from the rookie ostensibly to make him more like me, odds are I'm being dishonest.
