[idvusers] Threshold for closed circle in station model?

Hi folks,

Before I attempt to look through code that I don't know (in a language I can barely read), can anyone help with a definitive answer to the thresholds used to draw a "calm" circle around a station, a shaft with no barbs, and then the 5 knot increment for the barbs? (I assume that a "short barb" for "5 kts" is drawn is speed is >2.5 kts and <= 7.5, but I have gotten burned by an assumption more than once in the past!)

As always, any help is welcome!

Thanks,
Chris Herbster
