No, Gretchen Nordyke’s clearly shows a 5. Hussein’s looks like a 5 as well. However, there is no 5 in the manual. Also, the manual discusses boxes all the way up to 46 whereas Hussein’s bc has half that many. There must be a different manual with a different coding system.
I could swear we’ve been over that half cut off number before.
I agree that 5 is a clear possibility for the cut-off number. I do exclude 1, 2 and 3 as possibilities, at least to my eyes.
