      I ran predictions on NSV and CUSF (habhub.org/predict) for a 1500 UTC flight on this Saturday from a mid-Edmond launch (35.6450N, 97.48W) .   Both were similar.  NSV had a range of 85 miles and CUSF had a range of 88.9 miles.  Both landed southwest of Bixby.  NSV just east of US 75 near the intersection with 251st Street. CUSF was farther north (221st Street) and east (near Yale Avenue).  I used ascent and descent of 1000 ft/min (5 m/s)  with burst at 96,000 feet (30 km).

      I don't have Balloon Track at home.

      Has anyone noticed a discrepancy in the predictions between Balloon Track and the NSV online predictor?
      I’m running predictions for the UCO flight this Sat. and I’m getting a 10-12mi difference between the two predictions.
      I’ve relied on Baltrak in the past and I like the NSV version, but 10mi is a lot of error.
