Members of the forum. I am very conscious that there are rumours of a new measurement for bat edges, involving a semi mythical Queen Mother 38.61mm coin.
Norbs, I hope I am able to do you justice with this.

I think I should make it clear that it is not my intention to replace the current FPotE standard [50p on the bat edge, 27.3mm] measurement, more that when a rather special cleft appears, this new measurement of choice can be used.
So by way of example, please see a rather nice bat Indian bat with a 30mm edge, as demonstrated by the use of the current FPotE standard.

I think we can all agree that this is a decent sized edge.
I am also going to show you the new BES Standard on my semi mythical SAF Genus 100 which, you will agree is a BIG bat:
