As a hold pool swimmer, let me put one concept forward to you all.
As professional pilots, we try and plan for every eventuality. Granted, we don't always get it right, however we try our very best to make sure we're fully briefed before the TOGA button is pressed. We're professionals, it's what makes us, well, us.
So, why would an attempt at the BA selection process be any different? It is professional to understand the situation you are entering. It is professional to want to achieve the highest standard possible. It is professional to make sure you are prepared for what is coming.
Waiting for someone else to give you the answers or tell you how to get to where you are going isn't going to do anyone any favours.
