While I understand you wishing to hang on to doing the statistics, and even understand why, the fact is that grid numbers are really an artifice of the old commercial business model.
I expect before year end you will see that the reporting will need to be changed at least in some regards in order to keep up with the quickly changing tech.
With the advent of such things varregions and Kitely's HG delivery systems [which are also likely to have copy attempts in some regards], and the use of the megaregions, stats have only little probative value, and really only in commercial respects as a marketing tool...and even that marketing tool has less and less value to them, and is subject to all sorts of interpretations and padding, as other conversations here have noted.
As the old tech continues to take a backseat to the greater open Meta, such things will become more obviously passé, even for those who like such things.
I really see no value or relationship to using stats pertaining to the greater free Meta now, other than some kind of totals. I know Metropolis could care less about stats, and I am pretty sure Craft and Francogrid could care either.
And as noted, it hardly pertains to the Kitely model either. The paradigm is changing, and quickly.
The only internal use is to add servers if needed and keep the special access OS updated.
Anywho, time will tell, and in this year.
