Thrust/Airpseed. I fly all three variants of the Canadian pencil tube, they teach in training to pull thrust at 30ft but I as well had "big jet syndrome" (LOL) and would leave the thrust in too long. This combined with flying the top of the bug and a nice gust of wind = 2,000ft float...... I was cured doing billions of MDW turns in the 700 to realize to control airspeed over the threshold. I spent weeks diligently observing the airspeed over the threshold to finally figure out how much that plane will float if you are at the top of the airspeed bug with thrust coming to idle at 30ft... youll never get that plane on the ground.
Also something to think about, I know many CRJ operators have performance Ref speeds as Ref+5... which again, that 5 knots can increase landing distance 10-15%. Also Also, out of technique, If there is a gust, I still will leave the bug at Ref and fly the +5 or +10 to make sure I can control the speed back down to Ref over the threshold to alleviate floating. Seems to work so far.
