Hi Paul and Kye
I feel Kye's approach is the right one - the data might reveal some theory.
I guess that 'V' meant 'vertical'...
I note 'VB' could possibly mean 'Vertical Brisbane' - given that Rover have exclusive use of VB.
That's pretty wild speculation there.
Let's see what new data comes in.
Many thanks to Kye, and all contributors.
Only more serious research - or a breakthrough - will help here.
