Each team to receive a maximum of 40 overs, with each bowler restricted to 8 overs and the bowler's run-up restricted to 15 yards.
If two or more teams finish in on the same number of points in any of the first four places, the positions will be decided on the most wins, or if still equal, the most away wins, or if still equal the highest average run-rate per over throughout the season. Counties with the same number of points in other than first four places share the position.
Four fielders (plus the bowler and wicket-keeper) must be within the area 30 yards from the wicket for each ball.
