*The formulas
for calculating Standard Deviation, hours
needed to win, and bankroll requirements below are from the book
"Gambling Theory and Other Topics" by Mason Malmuth. I highly
recommend this book for a more in-depth discussion of this topic.
I. Overview
The [User]->[Sessions] and [User]->[Blocks] queries
allows you to view hands in your database sorted
by your sessions/blocks! A session is defined as when you sit down at a table
till when you leave that table, and applies to a single type of hands only.
A block is defined as when you sit down to start
playing till when you leave, ignoring table changes, and applies to all ring hands.
See differences for more detail.
Also, statistics on your sessions/blocks,
along with your win rate, standard deviation, and some confidence ranges
for your win rate, number of hours you need to play to win (come out positive),
and bankroll requirements are displayed.
Note that we recommend AT LEAST 100 sessions before trusting the data
produced. This is because with fewer sessions, the data generated is
dominated by short term fluctuations. Also, because your true win rate
and standard deviation can change over time (for example, if your play is
improving), we recommend that once you have collected several months worth
of data, to get your current true win rate, only use the last 1 or 2
months worth of data (or your last several hundred sessions)
by using the Sessions Filter.
The below screenshot and Usage/Tips are for Sessions,
but they apply equally for Blocks:
II. Usage
The data displayed for each session is:
A game is defined as being in the same session as another game
if both games are played at the same table, and are no more than "Max
seconds between 2 hands for them to count as same session." apart.
This can be set in the
[View]->[Options] menu.
The summary data displayed is:
The "Set Filter" button allows you to filter sessions, and only
view those sessions that you want. You can filter by the average
number of players, game type, date, time, session length,
and by limits.
Double clicking on any session will bring up a list of hands from that
session.
III. Difference between a Block and Session
A session is defined as when you sit down at a table
till when you leave that table, and applies to a single type of hand only
(example: Omaha hi/lo ring games only).
A block is defined as when you sit down to start
playing till when you leave, ignoring table changes, and applies to all ring hands.
You can have a block consisting of both Hold'Em and Omaha hands.
For example, if your current query type is set to hold'em ring hands,
and you view the [User Sessions] query, you'd see each session the
user has played at a hold'em table. If you play two tables at once for 3,
it will be shown as two sessions of 3 hours each, for 6 hours of total
playing time. Your win rate will be based on 6 hours of play.
If your current query type is still set to hold'em ring hands, but
now you view the [User Blocks] query, you'd see how you do each
time you sit down to play Paradise till when you stop playing at Paradise.
All ring hands will be counted, not just hold'em ring hands.
The current
query type is ignored when doing a [Blocks] query.
If you play two tables at once for 3 hours, it
will be shown as a single block of 3 hours played. Your win rate
will be based on 3 hours of play.
IV. Tips
Use the filter to change various session parameters, to find out when
and what situations are more profitable for you. For example,
you can see what times are the most profitable, what session
lengths are most profitable, etc... One great benefit of this is finding
leaks in your game. For example, you may find that when you play 4 hour
sessions, that you are winning less than when you play 3 hour sessions.
Maybe your play deteriorates after 3 hours, and you need to take a break
or stop playing after 3 hours! Discovering things like this could
potentially be very profitable to your bankroll!
Another good thing to do is to find your worst sessions, and view the
hands you've played in that session. For example, if you have one session
where you lost 66 big bets in one hour at a full handed hold'em ring game,
you should double click it to bring up the list of hands from that session.
Then see if you have made any obvious mistakes, or gone on tilt, or if this
was just an extreme example of variance (something that happens once in a
while) and not your fault!
Remember that a big bet is defined for no-limit and pot-limit
games, as double the big blind! When generating statistics, it is
a good idea to separate your no-limit/pot-limit games from your
limit games.
#106,856,420, "Izaza", won +$157.50, +15.75 BB, 1.36 hours, 12/28/2001, 41%
This displays the first game number in that session, the table
name, outcome in dollars and units of Big Bets (for no-limit and pot-limit
games, a big bet is defined as double the big blind), and total hours of the
session. If there is only one hand in a session, the time for that
session is set to 60 seconds. The date of the first hand in the session is
given, in CST or EST (time zone Paradise uses in it's hand histories).
The last number is the percentage of players who saw
the flop in that session, in the example above, on average, 41% of the players
saw the flop each hand.
Totals:
260 sessions 15739 hands 243 hours
Averages:
0.93 hours/session 64.86 hands/hour
Total won/lost:
+$1865.00 (201.50 BB)
Win Rate:
+$7.6851/hour (+0.8304 BB/hour)
Standard Deviation:
$103.0933/hour (9.9094 BB)
A 95% chance your true win rate is:
$-5.30 to $20.70/hour (-0.42 to 2.08 BB/hour)
A 99.7% chance your true win rate is:
$-12.20 to $27.50/hour (-1.08 to 2.74 BB/hour)
Hours for a 95% chance to win: 487 hours
Hours for a 99.7% chance to win: 1619 hours
Bankroll for a 95% chance to win: $935.50
Bankroll for a 99.7% chance to win: $3111.50
For this
data to be accurate, we suggest having at least 100 sessions. The
more sessions you have, the more accurate the true win rate estimate will
be (the range of your true win rate will be smaller). Also,
keep in mind your win rate and standard deviation
may change over time. For these reasons,
we suggest querying your win rate with the filter set to a specific
period of time, for example, your last two months (assuming you have
played enough hands in the last two months to be statistically significant).
