Difference in VP console to WD

Having just got my VP2 up and running again after my wireless repeater went down, I now see that the console records 105.8mm of YTD rain but WD YTD shows 89.2mm - blast!!! its tipping down now and the figures keep going up, anyway there is a difference. I seem to have lost some data in the period before I was able to move the console to a place where it could receive directly from the ISS, but the console although is now reconnected to my PC shows more rainfall then WD and I cant understand why there is a difference?

Did you have data logging enabled in WD? If so did the data logger extraction window pop up when you fired WD back up?

You can adjust your rainfall from Control Panel Offsets and Initial Rain…
