You have studied well, studi, and are to be commended.
Your airline has it right, in my opinion.
My present airline presents no particular guideance in this area, nor is any called for, as we (collectively) have been in the airline arena a very long time, and have the same general opinions as your carrier.
High speed aborts (especially at heavy weights) are the most demanding actions a Commander might take in his/her flying career and, for it to be done correctly, positive well thought out action is called for.
