You are using clientraw.txt for your “livedata”.
The http://swanston.maui.co.uk/clientraw.txt has 10 fields for rain-hour, they all contain 0.3 mm
The clientrawextra.txt has 24 fields for rain-hour, the first 9 contain zero , other 15 contain0.3 mm
Seems Brian, as the programmer of WD, has to tell me how I should calculate rain-last hour.
Probably I have to subtract the tenth = last hour value from the ninth one to get the last hour rain.
