How Does Your Average Session Win Compare to Your Average Session Loss

[Freightman]

For blackjack, a simple Excel sheet... Columns: Date, Location, Comps/Coupons, Hours Played, Hands Played, EV, CE, AV, Totals.

Add on a column or 2 of pertinent data fir the specific individual. Use filters to look at data by any number of criteria, or mix of criteria, including date, store, losses only or losses over a specific amount, same thing for women bs etc etc. Either download to apAccess, or refresh an Excel pivot chart to look at specific info on a continual basis. The permutations are endless. The data, over a large Nv period of time, can provide lots of data pertaining to the strength or weakness of your bpgame.

Though I don't go to this extent anymore, do not discount the value of the information.

My log has date, time, duration of play in 100 rounds per hour, casino, buy in, cash out, spread, rules including pen, and EV for those rules and spread based on cvcx. I have self calculating columns for win and EV/hr. They feed into a different tab with overall results.




Hate when that happens. The other night, I was playing and this happened. Then they came over and had a long conversation with me.

Take it it wasn't about the weather.

How about a blackjack army hoodie? Ya think?

Lighten up Frank. It's a call back.

What part of “Ya think?” connotes any real degree of seriousness?

Please consider taking your own advice before ridiculing others.

I once wore my BJ21 shirt to a casino. It had a logo of a pile of green chips with a shark tail circling them. The shirt was cotton and always came out of the dryer all wrinkled. I believe I paid something like $30 for it and that was 20 years ago. Never wore it again in a casino. I still think the shirt is somewhere in my closet.

I am running just under 1 STD up this year. I have had 16 wins over or close to 2 STD up, and only 6 losses close to or over 2 STD down.

My average win is $865 and my average loss is $338. Not sure that means anything, because I play different games (different rules, different table limits, a couple nice side bet games, etc). But for giggles, these are my numbers.

I do white rabbit aggressively, so I tend to have several small wins as the count drops in the beginning of the shoe.

This year, my average winning session is +274.11$ and my average losing session is -348.25$. Interesting. Most of the difference is due to not enough data points. I don't consider myself one to dig usually. I do, however, like to book wins. Sometimes I'll leave early just because I'm up and want to log it. I think that may be some of the cause of the 74$ difference.

58% of my sessions this year are wins, 42% are losses. I only have 109 sessions logged for the year though, so not much can be drawn from it yet.

Boy, these numbers look similar to my numbers from about 15 or 16 years ago. Over the years both my average win and average loss have been getting larger indicating that I'm simply betting larger than I use to.

My numbers from 2001 were average win of $155.53 and average loss of $232.48. It looks like a pretty bad year, but actually it was a winning year as a I won 71% of my 78 sessions that year. Back in those days my play was pretty much limited to crowded Friday and Sat nights.

Unless your average session time is consistent, its not possible to draw any conclusions. For most of my first 2 years, and I am often prone to it now, I tend to play longer sessions when I am losing. At times, I get to win the session and sometimes, I end up with a bigger loss.

If session time is kept consistent, I would expect a good AP to win between 60-65% of the time. If session times are not held consistent, an AP might win 80% of his sessions but his average session loss would be far greater than the average win session.

Fact is that for most, there is a high from a winning session and a low from a losing one. Thus, we try harder to make sure we have a winning session and thus, perhaps, play longer in some sessions. Also, when you are losing, you might fall into a trap and think the casino has you as a loser and thus there is no heat so play can end up being longer.

To me, this is a somewhat silly discussion. Not one person has defined what a "session" is, and most have said that they aren't consistent in quitting after the same time of play, whether they're ahead or behind. So, what's the point of the discussion? Furthermore, personal anecdotal evidence is virtually meaningless. Drawing conclusions from your personal results about mathematical concepts is a waste of time.

So, if you want the pure math of the question, see BJA3, p. 21, and, especially, pages 298-301, to see how to calculate the average win, when you have a win, and the average loss, when you have a loss, for different time periods (assuming, of course, as should always be the case, that session length remains constant, for the comparisons).

This thread reminds of this.

You want to invest $10k in the stock market, so you call two brokers. You tell them you want to put one thousand dollars in ten stocks. One is proven that 90% of his stock picks go up 10% at years end. The second is proven that 90% of his picks will be down 10% at years end.

Who should you invest with?

After further research you discover that the first broker's one losing stock went bankrupt, but the second broker's winner doubled in value.

So if you invested with broker one, you lost 10% and with broker two you made 10%.

So much for win percentage.

This year my largest win was $425, largest loss $700. I've played only 13 hour long sessions this year, winning 11 and am ahead $1670 all at $25 min tables.
