Comment(by bemasc):

 Replying to [comment:32 greenfeld]:
 > Of possible interest is that having an XO 1 share the Distance activity
 with a 1.5 seems to result in a ~0.1 meter measurement length increase,
 but it sounds like we are not trying to be that precise.

 That is an interesting result.  I expected this problem might occur, which
 is why I introduced a calibration bar that allows you to adjust the
 offset.  Unfortunately, I was unable to determine any decent programmatic
 way to identify the hardware in use on both laptops, in order to set
 default calibrations that give accurate measurements across different
 hardware.
