Oh, oh!  In 1997 I worked out the distance as 930 light years, but that was
without figuring a hundred years in parking orbit.  If we factor that in,
so the journey is only around 230 years, then the time dilation goes up to
4.11:1, suggesting the velocity is 0.97 c, and the distance is more like
850 light years.

LEG    RATE    TIME        TIME        DISTANCE
Boost  0.1 g   10 years     8 years      0.5 light years
Glide  0 g    880 years   214 years    853.6 light years
Boost  0.1 g   10 years     8 years      0.5 light years
TOTAL         900 years   230 years    854.6 light years

(The rates for the boost legs are simple speculation.  It doesn't seem like
the boost could be as high as 1 g, but it could be much lower than 0.1 g)
