said by mattmag:And who knows, really. The three could mean "Add 3 to each number" or "take away 3"........ oh my..
OR if he's so sure that it's a 3 number combination:
16 (-/+3) = 13 or 19
89 (-/+1) = 88 or 90
38 (-/+5) = 33 or 42
As for those saying to safe crack, well I deal with about 5 combination locks at work (3 to 4 numbers each). What I notice is a "tick". It's not heard as much as it is felt as I spin the disc. I don't feel it when I reach the number on the last revolution, but I feel it when I pass over the number while completeing revolutions.
