I've heard no solution from you, regarding the ACTUAL problem exhibited here. That is selection of the WRONG motor program (muscle memory???)
Did you offer one?
As far as 'my outfit' "where the PM pulls the reversers". (It's in OUR FCOM!) Can you point me in the direction of an incident/accident where our procedure has caused any problem? Because I can point you in the direction of MANY accidents where the PF has pulled their own reversers (or hasn't!!!!) and THAT has resulted in excursions!
Open your mind my friend!
It's about safety!
