In the grid, each row is a phase of the round-robin. The row count is equal to the number of competitors minus one, or twice that number for a double round-robin.
In the grid, each pair of cells in a row shows a single match, the Home competitor followed by the Away competitor e.g. A1 & B1 are the competitors in a match.
In Matches, each row is a match.
In Home or Away, each row is a competitor and the columns show match phases.
In a double round-robin all matches are repeated with Home and Away reversed.
Each competitor has a partner who will always be Home if the other is Away and vice versa. Use this if venue shares are an issue.
Partners are pairs of numbers from each half of the competitor list e.g. for a 10 competitor round robin, the partners are 1 & 6, 2 & 7, 3 & 8, 4 & 9, 5 & 10.
The tables will always show an even number of competitors. To facilitate byes, just pick any number as the designated bye.
If there are more than 4 competitors, no competitor should ever have more than two Home or two Away matches in a row. Beware other online tools that claim this, but fail when it's a double round-robin or ignore this consideration entirely.
Low numbered competitors are home in the first phase. It may be useful to give new competitors high numbers.
