Quote from a guy on pbnation:
At 3 ms, I can only imagine what you're doing to your marker D:
This guy's comment is missing about half the relevant data.
I'm more apt to guess that you've got a board with a cheater mode of somekind, or maybe your solenoid is locking open. Can you get the same crack at 15ms?
