I shoot enough and for long enough distances that my brain has an arrow trajectory ingrained. I hold Byron Ferguson in highest regard, but once you release then the arrow itself has very little to do with the outcome. ALL the work had to be done before that instant: spine, trim, fletching, form, aim, release. No matter what the arrow wants it is too late once it is in motion.
Maybe he should say: "become the trajactory".
I know that if the day's first target seems to be 30 yards I have to focus on a spot 6" higher than I normally would at 20 yards. The arrow is dropping much more than that, but my mind has to meet my brain halfway. ;-)
As Calgarychief opined: if you do a bunch of roving or small game hunting in cover you get to know what kind of window an arrow needs for clearance along its flight.
