I was wondering when someone would bring up the "double the grits"... shall we call it a theory? Where does that come from, anyway? My understanding, and I could be wrong, is that it came from the US distributor of Shaptons. Does anyone know any different, with regards to its orgin?

Regardless of where it comes from, we have very clear evidence that systems that do not double grits (Norton 1k, 4k, 8k or Naniwa 1k, 3k, 5k, 8k, 12k with the 3 and 5 being either/or/both) yield extremely high success rates and neither one doubles the grit at each step.
