Default Inherent error in tipping rain gauge?

I think it's actually more accurate are reasonable rates. Less chance of
evaporation emptying a nearly full bucket. I know my gauge will not
register anything for the "heavy mist" type rain no matter how long it
goes on for.

Where does the water that's draining through the funnel go while the
buckets are tipping?


Into one of the buckets, either the one about to empty or into the empty
one depending on the precise timing of the drop. The buckets flip (well
see saw) *very* quickly, at least they do in my gauge.
