Reply to "Purpose of the SCPF"

The reason for the rule is no one can measure say 5000 meters exactly. I remember a time when the SCPF wasn't used and the switch was made to include it for our measurements. I recall one of our long time Certifiers resigning. He stated we are not using "REAL NUMBERS".

If you google the history of the SCPF, You will find several interesting articles. One is posted on our BB.

This rule is used as a safety factor.
