I'm not -- I'm just more of a Conway's Game of Life expert than 99.9999% of the world's population. But that's just due to experience and invested time, not cleverness.

Could probably add at least one more nine to the end of that number, and maybe two ... the CGOL community is very widely dispersed geographically but it's really very small. There just aren't very many Conway's Life Expert candidates out there! For me to hit 99.999999%, there would have to be fewer than eighty people out there who have more knowledge about Conway's Life than I do

At least for certain topics -- like the reverse caber tosser, for example --

-- I'm fairly confident that I can list pretty much every person in the world who has a deep knowledge of the workings of 15-glider RCT universal construction ... and there are a lot less than eighty of them.
