Right, after thinking about this on the bog (where i do all my thinking) have come up with a slightly hairbrained idea.
My m8 once made a device that was a pencil mounted on a Scarlectric cars wheel that when it went round would press the trigger of the marker, so you could get a feel of how fast the marker could go.
Well, if you effectively make that but better, lol, and program it so say 60rpm fires 1bps, 600rpm fires 10bps etc.
Then when it comes to test a marker for a ramping chip, turn the wheel thingy on, at say 18bps, and find out with a radar thing if it is firing 18bps, if it is fine, its legal, if not CRUSH THE BLOODY GAT FOR WASTING EVERYONES TIME.
There we go, sorted, lol
