Yes the GPS does sometimes result in a recommendation of a startlingly close stripper guide. Joe claims that these close placements have been working out. I wouldn't use them myself . I would stick with the location of the choker using the 27 X , locate the stripper based on the string method and then locate the guides in between using the results of your stress test by whatever method you usually use for a good distribution based on action. I think the business of the concentric circles is way over emphasized and fuji's recommendation of placing the guides btween the choke and the tip at even spaces is somewhat thoughtless IMO.
So "The Saltheart Method"

is Tom Kirkman Method+ Fuji New Concept Guide Placement Method + Stress Distribution Method + Exponential Equations Method. My method works great every time!
I have not had the chance to read his (Croaker Joe) latest stuff on the KR guide placement system.
