Boathealer,
I did already understand that, but obviously could have phrased my question better. (Thanks for explaining anyway.)
What I really meant was "I know that some portion of loopers are not counted in that chart because they never joined AGLCA; yet oftentimes those numbers are presented as the definitive total of annual loopers (as if everyone joined)."
For example, I just read a looper blog last night, where they said "Fewer people loop each year than climb *Mount Everest!" and they used the AGLCA figure to represent the total number of annual loopers.
Not that it's a big deal, but I guess not being a "joiner" myself, for the most part, I bristle (only very slightly - soft bristles
) when that is taken as the definitive total. Again, no huge big thing, but since it showed up in the thread I mused about it.
*Apparently about 800 people climb Mount Everest annually, so since there are probably not ~600 "other" loopers it probably still stands, but was just an example of the AGLCA total being presented as the "true" total.
