Re: LNG owners with 3 or more Jem neons.
Um, why does it matter...?
From a purely statistical standpoint, there's really no good way to estimate this without doing a bit of surveying. I'm not really up on the production totals, but I'd take the rarest neon Jem, survey as close to a true random assortment of people who own it as possible (and there's no good way of obtaining that, as I think even posting a thread here would clearly be suspect as being a member at Jemsite probably correlates with owning more JEMS vs not being a member here), and take the % of people who own various combinations and extrapolate off the production totals.
What that tells you that's actually useful, I couldn't tell you.
