Plan Z dart from UTG hits the track

Hi 9's would be a fast run with a completely stock /6 in a full weight dart ..... real fast in fact.
Im thinking maybe it was a high 10 lol its been 20 years ago I do remember I knocked off quite a bit of time shifting with the Hurst shifter. Maybe it was 12 something down to low 11s high 10s. Either way it wasn't far off utg plan z.
