I don't know how I missed this gem!
I totally think you should kick out those fake weekend instructors like myself.
Then you will have to hire more full time instructors to handle the weekend capacity, and you will have to share more of your weekday jumps. The math will totally work out in your favor, trust me I am certified public accountant who pretends to be a skydiving instructor on the weekends.
I will get to fun jump more, so screw it, and I don't really care if you have to switch from Dinty Moore stew to Alpo because you suck at math.
