I am suprised that bandwidth needs to be used for this issue, if one would call 
this an issue.  Must I reiterate the differences between accuracy and precision 
in this case?  As stated immediately above, it is true that 2 points constitute a 
straight line however, the precision based on two points compared to the 
precision of three or more is significant in nature.  In science, we must neglect 
a certain amount of error in calculations due to inherent entropy but it all 
comes down to convincing the professors on one's committie.
