Very interesting reading Pete.
Would you mind explaining your SOP about the BUG -5..etc. I am just curious, in RYR we don't call anything until the speed drops below Vref, usually bug -5 (depending on the wind additive), and it is normally not required to take controls unless the arrow indicates further decelleration at that point, and the obvious thing that you have made a couple of calls, last one indicating your intentions to take controls.
Cheers
