Addendum to the two posts above ... I have been having problems editing these this morning (with the wierdness of an earlier revision finally lodging itself in place) ... but never mind.
But (just to be clear) when I say
all of the previous PM's in the first post, I really mean "all of the previous three PM's" (as we had chosen
three as our "Recent PM's repair check" sample).
And, at the post above "... as it would look back at only the last PM to see whether a repair was needed" ... would have better phrased as:-
"... as it would look back at only the last PM to see whether a repair
had been needed"!
Semantics? Not really. Just clarity, I hope.
