Steve W. is correct. There are a number of ideas out there for dealing with
this problem properly. While the mid-point approach mentioned in the original
posting addresses the issue, I don't think that it is statistically
legitimate. And yes, how come no mention of the Signor-Lipps effect? Here is
another article that might be helpful:
