That is a pretty large difference in detection. The top one is from Sky/Air, the other two from Tempi. The central one is from a tempest standing indoor but detects around 4 times as much lightning.
It is not a complaint, just an observation. Also hard to compare because an unknown amount is coming from the servers instead of my sensors. But it almost looks as if something went wrong with filling data from the server between 20.00 and 20.30 for the bottom graphs.
