Default Re: Spark plug gap...Myth? Fact?

Comparing different engines we have found them with as much as four degrees difference as to where the keyway is indexed on the crankshaft in relation to piston TDC and magneto coil position.
That comparison - was that between engines from different manufacturers, or the same? If the comparison was between different mfr's engines, was there also any comparison between engines from the same mfr or brand?

I love details.
