Hi all,

Happy new year to all.
I've been playing a BJ game with a house ege of just over 0.25%. Not bad by most online standards.
Anyway, I've been meticulously collecting my results for the past 6 months or so and according to this calculator (https://www.card-counting.com/calcrisk.htm ), my results are about 7.7 standard deviations from normal. Now I understand that calculator may be somehow flawed and that 2 sessions in particular skew the sum of the amount lost, but the overall results still seem to me to be pretty unbelievable.

Please have a look and let me know if you think it warrants a formal complaint.

Your calc on line 60 assumes that all wagers were equal to the average wager, but that is not so, so your total SD calculation is incorrect. It can only be calculated up from the individual wagers if they were of significantly different values.

Your wagering sessions of rows 26 - 27 MASSIVELY dominate. It may well be (I rather suspect) that even within those sessions, that there were some even larger wagers that dominated those sessions.
I did insert an average wager column and rows 24-27 were much higher than average.

Without trying to redo your maths, I'm afraid the results look pretty ordinary.
If you are enjoying the game, you're already winning.

Don't you expect to be cheated? You can't watch them so why would they not cheat?
