8.4.3.3 Cube statistics

This section provides a summary of the cube decision statistics: the number of cube decisions, missed doubles, etc.

1. Total cube decisions: The total number of cube decisions, i.e., the sum of no-doubles, doubles, takes, and passes.
2. Close or actual cube decisions: Similar to Total cube decisions, except that no-doubles are only included if they're considered close. GNU Backgammon considers a cube decision close if the relevant equities are within 0.25 from each other or if the position is too good.
3. Doubles, Takes, Passes: The total number of doubles, takes, and passes in the game or match.
4. Missed doubles around DP, Missed doubles around TG: The number of missed doubles around the double point and too good point respectively. If the equity is below 0.95 the position is considered to be around the double point else it considered to be around the too good point. If you miss doubles around the double point, it usually means that you double too late, whereas missed doubles around the too good point means that you're too greedy and play on for gammon when the position is not too good.
5. Wrong doubles around DP, Wrong doubles around TG: The number of wrong doubles around the double point and too good point, respectively. If you have wrong doubles around the double point that generally means that you double too early where you really should hold the cube, whereas wrong doubles around the too good point means that you double positions where you really should play on for a gammon or backgammon.
6. Wrong takes, Wrong passes: The total number of wrong takes and passes, respectively.
7. Error rate (total): The accumulated cube errors for this game or match reported both normalized and unnormalized.
8. Error rate (per cube decision): The error rate per cube decision is the total error rate divided by the number of close or actual cube decisions. Note that is different from Snowie 4 that defines the error rate per cube decision as the total error rate divided by the total number of moves for both players. In general, your error rate per cube decision will be lower in Snowie than in GNU Backgammon. Note that the reported number is multiplied by 1000 in the default settings.
9. Cube decision rating: GNU Backgammon will assign a rating for your cube decisions ranging from Awful! to Supernatural. See the description for the overall rating below.
