What looks like a high-cadence light curve is actually observations over several years, and each transit observed consists of just a few points. It doesn't help that the error bars are essentially the full-size of the transit. So the transit timing accuracy of the Hipparcos data is something like 1 hour and if you check, you find that including these data doesn't improve the period (or the subtle change in period expected from tidal decay), which is already known to 75 milliseconds from modern observations. Still, it's nice to see the transit in Hipparcos data.
