View Full Version : Std. deviation once again - online


10-09-2001, 09:39 AM
Sorry for bringing the subject up again, but i need a little help here.


As i understand the std. dev., its calculated on the pr. hour basis. But in reality a more precise way to calculate it would be pr. hand. I guess thats what we in reality does when we use pr. hour because we assume we play same amount of hands pr. hour from session to session. For practical reasone we just add it up to fit an hour. It might as well be pr- half hour or pr. 2 hours or pr. 100 played hands.


But if we calculated the std. dev. pr. 1000 hours of play, i guess it would be much smaller than 1000 times std. dev. for 1 hour.


I have read many threads here, where the swings online is presumed to be much bigger than in casinogames and it seems to be an accepted fact. But in relation to the std. dev., I would assume that the swings evened out much faster than in casinogames because, you play much more games pr. hour.


As I understand, its possible to play about 30-35 hands/hour in a casino (have never played at a casino - not available in my country), but online you can play 110-120 hands/hour.


I guess that, very shorttermed, the swings would be bigger online, but it evens out 3-4 times faster than a casinogame.


Is this right?


I have calculated my std. dev. to 66 in 2/4, 85 in 3/6 and 102 in 5/10, based on playing 2 tables.


Is this a high value in relation to casinoplay or others online results?


I have considered to calculate my std dev. separate from each table played. So when i have played 2 tables for 2 hours, i would register the results separatly, i.e.


table 1: +85 2 hours 5/10

table 2: -30 2 hours 5/10


instead of, like i do now, +55 2 hours 5/10, seeing the tables as one and just relate to the previous princip that i have played so many hands.


The separate table registration has the advantage that if Im playing 3/6 on one table and 5/10 on an other, i can separate the calculations to the proper limits and not have to stick to same limits on both tables to ensure a proper calculated std. dev.


What would be the most correct way to do it? Would i have to recalculate the std. dev. based on "pr. table" for playing 2 tables at same time? Do you think my std. dev. would change at all? If it changes, would it then be bigger og smaller?


If i do it separate for each table, what should i then do when changing tables. Playing 30 minutes on one table and then changing to an other. Can i registre those 30 minutes on the table i left and then start a new registration on the new one or would that affect my std. dev.?


And all this leads to an other assumption. If its possible to win 1BB/hour in a casinogame, should it not then lead to that its possible to win 3-4 BB/hour online playing 2 tables (everithing else equal), because again this is basically an expectation of win pr. hand played.


All comments appreciatet.
