I did say "change *that much*". Sufficiently ambiguous for me to weasel my way out of any evidence you can come up with. ;) But seriously, the only thing that matters is whether the job queue is persistently high, and if it is, that will be . . . well, persistent. If it spikes for two minutes and then drops back (how quickly do those job queue runners work anyway?) then who cares if that's not reflected in the stat? Average all the ten-minute samplings over the last day if you like.
Unless you specified that 96 seconds ago the job queue was X, 10 minute sampling will confuse even more. After changing a tempalte used on hundreds of pages, i'll go to see how much work i added to the job queue, if the data is older than 30-60 seconds i may need to go there, i'll have the dangerous think "it wasn't so much load".
