Actual total from the 5 inch check gauge was 27.0 mm, so the TBR was
under-reading by a considerable margin.

You might be interested in these figures for the Wokingham AWS
I have just been looking at the figures from the AWS at Emmbrook.
The TBR logged 23.2 mm in 32 minutes, but correcting for expected losses
that should be equivalent to 25.8 mm.
What is astonishing are the values for rain rates.
Here is the list of the one minute mean and max rain rates during the
storm, mm/hr (all times GMT, and time is minute ending at):
Time mean max
1809 12 16
1810 34 49
1811 40 46
1812 27 34
1813 27 43
1814 40 43
1815 40 49
1816 87 107
1817 101 177
1818 121 177
1819 154 314
1820 121 314
1821 127 506
1822 94 177
1823 101 177
1824 94 227
1825 148 314
1826 101 314
1827 20 36
The maximum indicated rain rate was 506 mm/hr at 1820z. Tips are timed to
the nearest 500 ms, so there is an error bar about 200 mm/hr wide at that
rate.
