Query: Better Eye Logic = Faster, Cheaper, Better, More

The Z Board upgrade appears to replace the speed adjuster on your Egg with some sort of advanced eye logic. It basically speeds up the impeller while things are moving past the eye. So, when your feedneck is empty, it turns at a speed that will load balls down when you drop a pod in there, or clear up a jam if one has occurred, but when you are shooting ropes, it speeds things up to feed balls as fast they are floating past the eye.All in all, I am very pleased with this inexpensive upgrade. My marker is capped at 17 bps, but I can get there easily now.The Z Board does lose one point for not having anything on the board to plug the hole where the speed adjuster used to be. It's a glaring oversight in the design if you ask me.
