Got that wrong about the W dimension (width) always being on the 96/48 axis. I looked through the cutting instructions of the stones I had cut in recent years before making that comment and all had the width in the 96/48 axis. But in the US 2020 Masters and Novices stones the width is in the 24/72 axis.
Anyway in the Grand Masters stone it’s in the 96/48 axis and I will be competing in this section for the first time.
