Martin, It occurs to me that maybe the answer might be to restrict the
outlet from the AWS to its tipping bucket. Small as it is, possibly it's
still too large to cope with a deluge. The weight of the rain in the
bowl would force the water out more quickly. Certainly my experiments
today seem to suggest this. I'll think about it for a day or two.


No I'd suggest the reverse actually. The problem with very high rain

rates AIUI is that the high flow rate causes some losses while the
xxxxxxxxxxxxxx buckets are in
the process of tipping (and also, I suspect, increased
losses due to splashing out of the buckets etc). In addition, a
smaller hole would block more easily.

So you're suggesting an even higher flow rate? I really don't follow
your argument there.

I think I'll try some experiments of my own and report back.
