Also reference how you counted them, clockwise or counter clockwise. There may be a standard, in a recent exercise with Jay West (who knows more on this than I do) the locksmith we went to to have some of Jay's measured keys made was used to people not recalling when they had the codes that Fred references.

A friend with a locksmith made keys from Jay's measurements and they have been verified (the measurements) to make keys from scratch w/o a master.
