Evapotranspiration losses cannot be limited to 7" during a summer
typical
for UKs temperature and wind profile, while meeting the
specification:
1" rain when you have 1" deficit.

So you say, I would beg to differ.

Mind you, anyone who says 'the UK temperature and wind profile'
doesn't
know much about the UK.

I think that he is having trouble getting his head round the fact that
the temperature/rainfall/wind profile can be significantly different in
places twenty miles apart.
As I said, rainfall increases by one inch a mile as you travel west
along one road round here.
