I'm curious WIll, is the 18.7mm value obtained from your new Davis VP?
The reason I ask, is I thought the metric settings accumulated
rainfall in 0.2mm increments, so I would have expected 18.6 or 18.8mm.

The Davis VP uses 0.01" increments (there were lots of bits of paper in
with my VP saying so!), so 0.254mm. Obviously all the nasty converting
to/from metric/imperial can be done automagically so they just make the
one size.
