We got sidetracked.  Lets go back to the original email:

My comment:
Extended geographic range usage of any conformal projection is a contentious 
issue as 
any resultant grid system has sufficiently large scale errors as to make the 
Cartesian usage of the grid very questionable.
Your comment:
This is true of any projection. It is true that conformal projections carry an 
inevitable disproportion of areas, but that's not related to scale error.

My sentense had nothing to do with area and by Cartesian usage I was denoting  
measuring distances, azumuths, etc. from the Cartesian data and it certainly 
seems that scale error greatly affects these measurements.

What got me sidetracked was your non sequitur second sentence in the sense 
that I did not mention area in my cited comment.
