MFT/3 Hole spacing to Deg of Cut

[land_kel]

Not sure if this has been done before, but I did a quick excel spreadsheet on degree of cut using the MFT/3 hole spacing.  I attach a .pdf of this in case anyone finds this interesting or useful.  If errors please advise and I'll correct.  I'm trying to figure out an easy way to cut 22.5 deg ( 1/2 of a 45 deg.).
