AFD's and aircraft piling up in front of the runway

For those who create afd files with Afcad, i found something of interest tonight to solve the problem of aircraft piling up on the holding node. Despite the holding line the node should be within and not further away from the runway then the runways width. No need to put rows of dots in front or behind the holding spot, in fact, use as less as possible nodes and believe it or not, framerates will rise.Good luck, in case someone mentioned this before, pay no attention.
