If you mis-anchor for one pass, say 1 foot short, both sides of the tape will still show you have enough length. So, you may measure what you think is 1,000', or 304.8 meters, but it is actually 999' or 304.45 meters. Appears that you have measured correctly, but without pulling the tape a second pass, you may make a mistake.
Duane, You are absolutely correct. Reading the tape on the metric and imperial sides may help catch errors in reading the tape. It won't catch errors due an end moving or slipping from the tire, or if the vinyl tape moved. Measuring forward and then repeating by measuring backward will help catch most of the tape measurement errors. -- Justin
