PM2.5 Map Value Differs From Chart/Widget?

Hi folks,

I’ve spotted that the map value markedly differs from the shared chart/widget/dashboard. For example, currently it’s showing as 3, whereas the others are showing zero. The map shows it’s using the EPA formula, but that correction is also applied to the other data sets.

I’m at the centre of the map in Fleet (you can click on that to get the historic map data)
My shared chart

Anyone know why the difference?

Thanks
