Lawn Speed Calculator
The speed of a lawn is taken as the time for a ball struck the length of the lawn from the boundary line at one end to just stop on the boundary line at the other (35 yards). The time in seconds is the plummer value and is generally quoted to the half second. The faster the lawn, the longer the ball takes to come to rest.
In practice, it is difficult to hit exactly 35 yards but easy to hit a ball so that it stops somewhere between the boundary and one of the outer hoops. Pace out the difference from the boundary and use the table below to find the plummer value.
Example: If the ball stopped in 10 seconds at 31 yards, look down the 10 second column and you will find the speed on the 31 yard line which is 10.6 Plummers

Less than 8 is unplayable. 8-9 = Slow, 10= Normal, 11/12 = Fast, 13+ = Very Fast
