I know, when I recently went for a BG Fit (mostly to get a second opinion on my position, only raised my saddle 1 mm and 1 cm to the front) the "fitter" too told me that cleat position is a personal thing. But what I simply wont is someone to tell me that "this" is the best position and I'll go with that. Now I basically can't decide and it feels that all the different theories has its pros and cons when I test them.
BG Fit can be great or it can be awful. They basically teach people to use a goiniometer, which isn't really that relevant most of the time, and how to question them/screen them for basic functionality problems and use a video camera to observe their pedal stroke. In bad cases, the fitter will actually recommend Specialized or other products to correct the problem before actually trying to correct it with the individual's current equipment and base their results on the gear not on the changes. In even worse cases they do both changes at once and can't trace what did what.
If a good fitter can't confidently recommend you a specific item position with sound advice based on your personal factors then they're not a very good fitter. Then, if you try their advice and it doesn't work they should have options for you and be able to adapt.
With that said I used the spindle slightly behind ball of foot protocol. I spent a long time going off of feel, then read Hogg's article and miraculously noticed that my most preferred position was actually right within his guidelines. I tried my cleats way rearward and didn't like it for many reasons.
People also have to remember that cleats are just one thing. A bad saddle position can cause even more bad feelings, such as those listed above. I'd get the cleat OK, and then worry more about saddle position.
Don't take me too seriously. The only person that doesn't hate
