and this increases dramatically,since not so many gamblers are playing the best way,I have seen many having 5-10% of the total wagered lost
I agree, the biggest mistake that people make is to leave when they are losing (or betting much more than they can stand if they face a losing streak). In that way, if you are 10% down, it is supposed that, at long run, you can recover to (at least) that 1% House Edge.
1) Player made 100 bets x $10 = $1000 wagered and unluckily hit a temporarily 10% House Edge = $100 loss.
2) Player continues to play as you advised attempting to reach the 1% House Edge to "recover".
Let us assume player makes another 10000 bets x $10 = $100,000 wagered and reaches the 1% House Edge = $1000 loss.
So even if the player reached the statistical 1% House Edge after 10,000 bets, he still lost $900 more compared to stop playing after he unluckily catched a 10% House Edge.
