Vinny's Allotment Plot

Are you sure about the length of your "pace". "Paces" used to be approx a yard, a metric pace would be 39". On uneven/frosty ground your pace may not be a standard one.
With little legs my pace is much less than 39". According to the kitchen floor tiles, its less than 2' - about half a metre.

I did 'John Cleese' paces which are a metre.

When I first started working on a Sports ground which had eleven rugby and football pitches my boss and I went out to mark them out. "Where's the tape sez I?" "Just follow me son he sez and stick a peg in where I put a heel mark in the turf."

When he retired I took over and started using a tape measure. I was surprised to find that his markings were spot on!

The only problem was that all the pitches were parallelograms as they hadn't been squared off. Referees used to pace the dimensions and couldn't understand that the sides and ends of a parallelogram can be the same size but the pitch can be a mile out of square!
