Excuse me here. I don't buy this. These numbers are _not_ measured numbers but
calculated "factors". Now, since a single factor "result" has a restricted
meaning and since you want to calculate even further the average your question
of accuracy is not that important. Since the average 1.7 is with plus/minus
anyway, it wouldn't help much if we would have 1.71 as the average. Or what
would you think?
