I built a tipping bucket type rain a while ago. 0.5 mm of rain per tip which
activates a magnetic reed switch and it is then logged.

I have an official Met Office funnel type rain gauge which I use for all my
rainfall measurements.

When I compare the two I find that the tipping bucket gauge generally
under-records by about 10%.

My knowledge of mechanics is non existent but is it not possible to make it tip
at approx 0.46mm and log 0.5mm, thus making it record more accurately than -10%?
