Dick has the conventions for hornpipe speed wrong. They're in duple time, two beats to the bar. So this:

Fisher's Hornpipe

which is taken at a pretty normal speed, has 64 bars of music in 88 seconds, which translates to 87bpm.

148-150bpm for a hornpipe is insanely fast if you mean 2 beats to the bar and much too slow if you mean 4 beats.
