The exact dimensions of the innermost groove and outermost groove are 2.37500-inches and 5.75000-inches. These equate exactly to 60.3250-mm and 146.050-mm. When you plug these into Baerwald's equations the null-points to six significant figures become 2.59835-inches and 4.75951-inches. These equate to 65.9980-mm and 120.891-mm.
