Due to recent releases, you may find some of the contents of this online manual, including the video tutorials, to be outdated. Specifically, it's important to note that the current Mac version of PokerSnowie does not yet contain all the features, since the Hands Import and Hand Range are not yet implemented. However, our team is working on it. We are also currently in the process of updating these materials. In the meantime, you can get a more accurate description of PokerSnowie's features on the various platforms by visiting the Downloads page and try out the software.
The error rate gives a score for how well the session was played. It is independent of the actual outcome and only based on the skill of the player.
For every betting round, the error rate sums up the EV cost of all errors, divided by the number of moves played. So the smaller the error rate the better.
Please note that the sample size needs to be big enough to get a significant error rate. Usually 5K to 10K of imported hands is enough to get a stable error rate.
Very strong high stakes players have an error rate of around 7 in ring games and 5 in heads-up games. Less experienced players and beginners often have an error rate of over 20.
A blunder is a costly error. The threshold for when an error is considered to be a blunder can be set within the options menu. By default the threshold is set to an EV loss of 2.0 big blinds.
The link 'Browse your blunders' lets you conveniently browse through all big errors, so that you can efficiently learn to avoid your biggest errors.
Profit and Loss
This page gives you an overview about the outcome of the session. The profit is calculated disregarding rake, with rake then deducted from that number.
The total profit is split into showdown and non-showdown hands.
Here the error rate is broken down into the four betting rounds. You can quickly see in which round you gave up most EV.
Note that you can click on the number of blunders and errors for each round. This automatically sets the filter so that you can browse through this error type.
The error rate measures the EV given up. You may, however, have a good error rate and a poor balance as a result of the weak/medium/strong ratio. The balance page shows you how balanced your play has been.
The 'Call' block compares your number of calls with the number of calls PokerSnowie would have played, split by each betting round. 100% is the perfect value, a number higher than 100% means that you called too often and a number lower than 100% means you didn't call enough.
The 'Bet' block does the same thing for all your bets, but split by bets with weak (as a bluff), medium and strong (for value) hands. Again 100% is best, but additionally it is important to have as similar a score as possible for each weak / medium / strong bracket. 100% weak, 100% medium and 100% strong is best, but for example 150% weak and 150% strong is a lot better than 150% weak and 50% strong. 150%/150% indicates a too high frequency of betting, but at least the ratio between weak and strong hands is right. 150%/50% is very bad, the balance is quite wrong and the opponent could easily exploit this.
The 'Raise' block has the same structure as the 'Bet' block.
Note that you can click on the numbers below the percentages, which is the number of times the player actually played that type of move. This automatically sets the filter so that you can browse through these specific actions.
Several statistics are shown. When possible, the stats of the player are compared with the stats PokerSnowie would have produced given the same situations. That way, it is easy to see how the player should adjust.

Number of times the player made a bet or raise, divided by the total number of calls.
Fold facing bet
Number of times a player folded to a bet or a raise, divided by the total number of situations where the player was facing a bet.
