to some highly inaccurate maps, especially in summer. It was the
extreme inaccuracy of these maps a few years back, that led me to
realising Scilly was double recording rainfall.

But Scilly does have their own weather station IIRC?

Hard to believe they never thought to cross-check!

The MetO station is the only one on St. Mary's that I know of. It was double recording rainfall for 10 months, from 1st Nov 2008 to 16th Sept 2009 even though I reported the problem after 4 months, it was so obvious.

There's also the AWS on St Martin's.
