The procedures for entering the scores varies depending on the event type and the scores being entered.
Use the [View/edit scores] option to enter scores manually or to change the scores obtained from your scorer files. From the edit screen you can also use the [name wizard] to enter player's names. This is much easier than entering the player numbers on the final scores screen.
For the ratings to be calculated correctly all pairs/team must have scores. The easiest way to enter the scores manually is to de-select all items, then just select the scores column and enter those.
In addition to the scores, pairs results must include the % value. Use the [calculate %]
button after the scores are there so the percentage is present. If your scorer has provided this already do not use this option as the scorer value will be more reliable.
