Hi David

I think my team (the Tang Tang Tintacks, or White-fronted Chat squared) did
about 600-700km for our 209 species in Victoria.  Maybe birds/km would sort
out a few of these expeditionary teams! - that's about 0.3 birds/km for us and
0.1 birds/km for you.

It seems to have died in South Australia and Tasmania.  Western Australia has
been quiet for a few years, and we haven't heard any reports from Queensland
this year.  Qld has it's own QOSI Twitchathon as well though, at a slightly
different time if I recall correctly.

NSW seems well and truly alive and vigorous, and the Victorian event certainly
had a major revival this year.

This handicapping discussion has been had a few times, but I'm not aware of
anything coming from it.  I thought that the North Queensland group of BA was
supporting a national trophy last year, but haven't heard any more about that

I think averaging the previous "x" winning scores in each state or region is
probably a reasonable way of comparing widely separated geographic locations
(x = how ever long the records go back).  I think this was the method settled
on for the national trophy.

It's interesting though that the winning totals over recent years in Victoria,
NSW and North Queensland have not been wildly different.  A total of 205-225
in a 24-hour Twitchathon in eastern Australia seems to be a winning one, 
of where along the line of latitude you find yourself.
