This lag is a different lag, it happens at a set amount of time. One way to test this is get a jenpie in an ore field and target a roid, cycle through them with the D key. You will see a roid hang up for a couple seconds before moving to the next. Depending on how fast you cycle through them, its always the same number of keystrokes, it happens to me around 12 roid cycles.
I have only tested this on one system, and it could be client lag on my end.
