I realise that, but if, as others have done, you put a 140mm funnel as a collector the area alters considerably and so does all the arithmetic, remember too that if you merely glue an extension to the outside of the collector you have possibly added 2mm to every dimension. This would mean that your collector area would go from 55cm2 to over 71cm2 nearly a 10% increase in area and necessitate a rework of the arithmetic in the arduino sketch. Accurate calibration in last post of this thread.

It seems that FO recognized the problem, at least their new weather stations come with rain gauges with large side walls.
When possible, I recommend doing this procedure.
