Reply to "Steel Taping Puzzle:"

Pete, I can see the marks for 80.8 cm and 80.9 and I think you could reasonably interpolate to get one more decimal place-- but I don't see how you could pick out 80.815 cm (i.e. 0.80815 m). Or maybe you look at 1/5ths of a millimeter, and if it's just under one fifth then estimate is 0.15?
I'm open to a new way of looking at it, I'm just curious about it.
