only the vehicles that i pulled the trigger on appear on the data summary log, so lets say a ball park figure of 750 vehicles past in the 1 1/2 i was there i only formed an opinion that 37 were over the limit
Indeed, but presumably had more of them been travelling at a speed high enough to attract your attention, you'd have pinged them as well. So of those 500-1000 vehicles which didn't appear in your log, isn't it fairly safe to assume that most of them would be under the limit?

remember there is a difference between the posted limit and the prosecution limit,
I know, but that's not the point. Someone travelling at 33-34mph might be under the prosecution limit, but they're still over the posted limit, which means they're just as guilty as the 35mph+ drivers of not doing what you want them to do - i.e. slow down in an area which your bosses have deemed unsafe.
And forgive me if I'm being thick, but I still fail to see how a simple collection of one-off speed measurements taken at some distance from the school entrance over a timespan considerably longer than the period during which the entrance is in use, can then be used to apparently criticise drivers for not slowing down outside a school. If you've got additional data which shows all of those over the limit pings occurred during the shorter period when there were kids milling around, then that'd be a different story, but the data you've presented so far doesn't lend itself to that conclusion.
