I note that the chain doesn't have the 'step' in the gullet - that is the way I do my chains, however, I'm just a firewood hack who hasn't tested heaps of chain variations.
From reading some comments, the 'step' is to break up the chips so that they will feed through the chain easier. I don't know, does it?
I started really cleaning out the gullet when I noticed where the wear marks were. The chips (Ozzie hardwood) would smooth out the machine marks from the file where the chips rubbed hardest against the cutter. I felt that if I removed those areas that there would be less resistance to the chain moving through the wood.
Am I correct? Or, does a small step actually aide in reducing resistance?

True, unless I'm noodling the chips aren't very long. At least not like if I get hooked into some softwood.

Using wear marks to know where to remove material is one of the best ways to make a chain faster and smoother. I like to completely blacken about half a loop of chain with a sharpie and then make a couple cuts to see where it gets rubbed off. With a brand new chain there isn't much to start with and you'll see very quickly why they "stone" chain for racing.
Skinny isn't always faster, in fact it can be much slower.

Could you expand on that comment? It seems contradictory, that is, by stoning the chain (making it skinny) may not make it faster. I must have missed something...
