How kind of you to post this!
Thank you so much.
I'm a math guy at heart, and have been coming up with reasonable cipherings. But it's always helpful to find others I respect chiming in, sometimes with better and/or more reliable approaches.
Enjoying.

P.S. When I earlier mentioned that I saw a disconnect, I should have pointed out that when we delight in a large gain in U.S. pricing, I don't often see it reflected Down Under. I don't understand that. But you're right about prices there and here are in balance.
