What are the odds of this working this well so far

Have been playing a stop win stop loss strag. realize that long term only counting can give advantage in BJ. but sucess so far with this over 275 hours in casino and up 87 units........also over the years have kept up with this on a computer game and it has worked at same clip ( % ) that has about 800 hours so combined 1075 hours and up about 240 units according to records.....what gives?? again no it cant last but how can it work ? this long ....flat betting also no raises double as basic strag dictates thanks ....

Don't have numbers directly in front of me, but to show you how meaningless 200 some hours are, consider this example:

"Let a person play 40 hours a week, 52 weeks a year, less 3 weeks
"vacation", 13 "paid holidays" and 8 "sick days" at 85 rounds per hour in a 6 deck, S17, DOA, DAS, RSA, LSR, 75% penetration game. This
is consistent with a "professional" player. Let this "professional" use a decent 2 or 3 level system, and further assumes that this player plays all hands. For a "moderate" 1-12 spread, the player still has around a 15% chance of behind DOWN after a years play."

Now turn it around, let's say you are playing a REALLY BAD game, and have the disadvantage equal to the advantage the above player is generating. That means you have about a 15% chance of being ahead after about 1800 hours of play.

After 287 hours of play, your 87 some units ahead, could all disappear in the next 20 hours of play and it wouldn't even be a stretch in the normal variation you find in the game.

So I would say your results are about 50/50. 50% of the time you will do better than you have, and about 50% of the time you will do worse (sometimes much worse).

Of course, since you are using STOP wins and STOP losses, it will probably take you a couple of years to get in 2000 hours to even start to see where this system is really taking you.

275 hours in casinos but again about 800 hours of play over the years on computer game result similar up about 24o units.....does this change odds lower than 15 % or no

Yes, you are probably pushing less than 5% chance. Really need more details to the exact game for a real answer.

However, I would point out the following:
You say 800 hours of play. Are you actually playing 800 hours?
A strict defintion of 800 hours of play would be 800 hrs X 100 hph. = 80,000 hands. Have you played that many hands?

Even if you are flat betting, that means 80,000 units wagered for a 240 unit profit? That 240 profit equals 3/10ths of a percent of what you have wagered. About the only only thing interesting is that you are slightly ahead instead of slightly behind.

What has your lowest low been? Since you are playing a computer game, I take it there is no way you can go broke, so no matter how much you lose, you can keep playing, eventually win it back -- see that you are ahead -- and then eventually lose it all back -- win it back, etc. In real life, your empty wallet keeps you from getting lucky and temporarily winning it back.

It would be reasonable to expect a typical counter to be working on doubling his bankroll for the 2nd time after 8000 hours of play (with a little luck). You have had a LOT of luck, and are showing 240 profit.

SOTSOG yes have played 800 comp game hours (home) and 275 casino games went back to records and unit count up is 276 units comp game 800 hours of time and 87 units casino time total units up 363 .....was in negative #s on comp only once at the begining after about 10 hours ....realize this is amazing luck but how amazing is my question % wise....thanks
