Is it not the case that this is a very new process in its infancy, with all the inherent inaccuracies thereof? We are in aviation, an ever evolving environment. This is one such area that is not an exact engineering science, like much of our nuts & bolts and aerodynamics we are used to. I'm sure there will be much try & test it follow up research after data is examined; much suck it and see and we learn from it scenarios. It is the beginning of a whole new experiment. Let's treat it as such and take a strong modicum of care in your decision making. It's all only guidance; there are no guarantees, just like with there old system. It is not an RTOW equivalent for landing.
