If you've enabled the HANDicap option, you'll be asked to set the handicap factor. The higher the factor, the bigger a handicap players will get. Choosing 100% means that a pair who averages 45% will get 31.2 more matchpoints for a handicap than a pair who averages 55% (on a 156 average). We recommend 80%, otherwise a large handicap will become the dominant factor in who wins.
After you've picked the percentages, you'll be asked to tag which sessions can count. This will allow you to exclude afternoon games from the calculation for an evening handicap game or not count percentages in a 0-100 game for determining the handicap in an open game. Tag the appropriate games by using the arrow keys and pressing space bar to tag or untag. Press F9 key to accept your choices.
Next ACBLscore will ask how many percentages to use (from most recent to ancient), you may choose from 1 to 999. Don't use too large a number, since the older the game, the less the percentage will reflect the form or ability of the player. It will also ask for a minimum number to use for calculation. If it encounters a player without enough percentages, it will ask for your help.
Now you may enter the names. After selecting a name, ACBLscore will display the number of percentages found and the average. If that player doesn't have the minimum number of percentages, ACBLscore will ask for your guess on their average percentage game or their desired handicap percentage. To assist you, a Handicap table is available. Press F9 key to accept the revised handicap figure.
