Mainsheet eye measurement

I'm planning to change the rigid eystrap on my boom with a soft strap made from a bit of cover left over from a tapered spin sheet. I knew of this diagram in the class rules and the 1 inch width rule, but what about the 15mm bit? It says "nominal" on the right of the diagram and is not mentioned elsewhere that I could find. Does that mean it's not actually controlled by the rules and is just a recommendation? It would seem (to me) pedantic for it to be controlled, but there is a measurement in the class rules....

Speculation: that measurement was left ”nominal” because it changes with the thickness of the sheet, which in turn is not restricted. Also, there’s no advantage to be gained going much shorter or longer.
