Hi! I'm glad you're performing well and having more luck on Pokerstars (?) than most regs at the limit!
I did a database analysis on NL5 ZOOM Full Ring last year and people I considered good regs were making only 3bb/100 on average, while people I considered worse, more ABC regs, were making 2bb/100 average over a sample of 400k hands, but it could been because I was a 6bb/100 reg at the time and maybe getting a small edge on them so maybe lowering their winrate by a little
Big longterm winrates are achievable if you're a complete psycho /slash/ crusher, but for a typical winning player, they're less than you'd expect in today's ZOOM
