A select few already know, but I've been writing a small piece of software (PC only I'm afraid), that takes your arrow's scores & gives you an estimate of your expected performance. You can read a little more about it in
my journal, or just grab
the zip file & play with it yourself.
I'm going to continue to tweak things (I have a a couple of bits in mind tonight), so although the link will remain the same for all releases you might want to check my journal to see if there are new things/bug fixes from time to time
