Some good information. If the user can figure out what he is doing to cause the resulting conditions and alter his ways, there may be some value there.
My personal experience is that many people think cutting wood is hard work and they don't stop trying to cut wood until they're too tired to continue destroying the chain, bar and sprocket. The best way to cut wood is with a sharp chain and clean, lubed bar. When they are anything less, productivity loss and equipment damage isn't worth the ten minutes it takes to clean the bar groove and sharpen the chain. Because you'll be stopping soon anyway when it won't cut at all...
