Vref+5 at 50' is the target, as you are doing.
Nice day your too fast consider the last 50 feet
Typical Hawker Vref 115KIAS V squared = 13225
+ 5 knots for the wife/kids = 14400
Difference is 1175 as a percentage of 13225 =9%
9% more lift energy to go somewhere, where is it eventually going to go? Brakes?? Runway ??
Might work on your boeing though
