[QUOTE=KimLee;7352]Sounds like you were a bookie.
Using your average figures, suppose you made 548 bets per year with 6.5% EV and 1 unit standard deviation. Then your mean is 36 units and standard deviation is 23 units. You have a 6% chance of losing in any given year, and a 97% chance of having at least one losing year in 51. And this is optimistically assuming your bets were equally weighted.
Some guys might grind matchplays all week and then blow it on sports each weekend. As long as they bet within their weekly profits, they will never lose.
Other guys might win consistently at moderate stakes backgammon or poker. But then they could find themselves with a huge edge in a big game and bet it all. For example, a good online poker pro might plausibly win $250K and then blow it on WSOP tournaments. One "name" pro lost $1MM of backers' money in tournaments fees.[/QUOTE]
Way over 2000 bets a year. Probably around 4000. Plus (how many times do I have to state it?) that is VS the WORST rogue lines we can find. Betting stale lines and/or against inflated spreads on steam games, we improve on our 54%+ vs Pinny by at least 2 %. Run those numbers.
