"Default" Math Vs "Legacy"?

What are we calling the new default Geo-Tol math? "New Math"? "Default Math"?
I remember this gun fight a loooong time ago, it ended up bad for Hexagon and us also.
what I mean is:
The "New Math" best fits a little too aggressive for me compared to "Legacy". Last time I had reports coming out with perfect true position our customer Lockheed Martin mopped the floor with Pc-Dmis and started the whole ISO Best-Fit shootout, disallowing us to use Pc-Dmis best fit algorithms. The "New Math" best fits also. Here is a comparison:

What do you think?
and can we come up with a disparaging term like "New Math" other than "Geo-Tol"? or "Geo out-of Tol"?

thx

I think more correctly, the topic I'm trying to bring to discussion is:

"New Math" performs a best fit calculation, if you are giving direction to a set-up machinist, I would consider using "legacy".

What are your feelings?

I tend to use legacy as much as possible as machinists want to know where a feature is without using best fit or MMC or LMC. The need pure XYZ coordinates to make the part. Final inspection programs are a different animal and I will use whatever the software has available, I do not use XactMeasure unless it absolutely necessary as it has burnt me more than once.
