That thought has crossed my mind, but the Davis ones tip every 0.2mm,
so it's probably not such an issue. In fact quite often a heavy due
can produce 0.2mm some mornings.

Obviously a tipping gauge will always under-read the precipitation - I
guess more so when the rain is heavier. Where does the water that's
draining through the funnel go while the buckets are tipping?

If we start looking for too great an accuracy, are we not in danger of
only looking at the area covered by the 6" diameter of the bucket? The
level of rainfall may have been different in another part of the garden.
