Fairly often I see lawn bowlers practicing adding
or subtracting a yard to their deliveries on a rink with cut up yellow tennis
balls marking the intervals. I’ve done
it myself. My judgment: it’s a waste of time until you can consistently deliver four bowls the same length (within a
yard). This was so obvious once I thought
about it. Delivering with exactly the same weight can be expected to be much, much
easier than adding or subtracting weight, but who can consistently do it? Certainly not me- yet.
