What you can be sure of is that on all these occasions it is highly
unlikely that the gauge was in the wettest spot.

Interesting that there is such a difference between the highest
1800-1800 24-hr total and the highest 0900-0900 24-hr total. Almost
invariably when somewhere is reported as having had a record wet day it
is the 0900-0900 24-hour totals that are being considered, although
this is seldom explicitly stated. The figures above show how misleading
it can be if only the 0900-0900 totals are considered.
