Depends on the operator, in this case the winning hotsaw was running 404.

Having nothing but questions, people always say .404 is stronger.
Isn't the dimension that .375 and .404 differ a length measure? So more meat to resist stretch? Is that how chains are really going to fail because of HP?
Thanks.
Yep. Look at the component that would break, the tie strap. Is it thicker om 404 than .375? Is the preset rivet thicker?
I think chip clearance and length of individual cutter strokes is also part of the equation. Once a cutter gets full it quits cutting despite raker settings. Really opening up the gullet area on the cutters will give you faster cut times in larger wood. That might give the nod to 404 compared to 375 in some wood conditions.
What about .404 chain in .058 gauge? I don't know if it's very easy to find anymore, but I have an old Pioneer chain of that size. I haven't measured but it appears to have a narrower kerf than the .063 on my 090.
