...He needed a sample of, at least, three---three watches...
Yeppers, back when I was in the materials testing biz, we'd say "one is an indication, two is a trend, and three is a test."
I worked on one Corps of Engineers project where my job was to run tests to confirm the results the testing guys got. Truly the Department of Redundancy Department. I was essentially testing the testers. I had a lab trailer set up next to theirs on the jobsite. (Their client was the contractor; my client was the owner - the Corps.) We ran a LOT of soil, soil cement, and concrete tests for those 9 months. And if something passed his lab and failed in mine, there was even more procedural redundancy to figure out what went wrong. Thing is, I had previously worked with the guy I was supposed to be testing against, both as a co-worker and a client. (We were good friends who were both laughing out loud the first day I rolled onto the jobsite and we saw it was going to be the two of us in these "enemy" roles.)
If either of us got questionable results from a test, we'd get together and figure out what had gone wrong and decide if anything needed to be re-tested (or rebuilt) or if we should just write off the anomaly. We were hired to be adversaries, but instead we just worked as partners to get the owner a good product...even if it meant not quite following the rules to the letter.
(It also helped that the head engineer for the Corps on that job was a common-sense guy who didn't get to hung up on procedure, either. Like us, he just wanted a good product.)
Sorry for the threadjack, Chuck. Glad to hear you've saved your planer from that pile of worn-out power tools you've got stashed behind your shop.
