Nobody knows?
This is the depth guage tool that I use. Very similiar to the "Husky" version. I like it...
.... I would think the plane of interest is wood/top of cutter to top of depth gauge. Should not this always stay constant? How far yet down to the bar doesn't seem would matter?

Why the 'progressive' concept? yes the tooth gets shorter from the bar as it is sharpened back, but since the reference plane is the wood being cut, I would think the plane of interest is wood/top of cutter to top of depth gauge. Should not this always stay constant? How far yet down to the bar doesn't seem would matter?

It is the same as the Husky guide, but a raker guide only, not a combo......
Believe the progressive concept was Carlton's. I think this was off their website a few years ago.
It can be considered as setting the angle of attack of the cutter to the wood. The cutter and raker do not stay pressed to the bar but make interrupted dips into the wood. The greater the angle of attack the steeper the dive into the wood. Probably fairly accurate for round filed chain but depending on side plate hook, that progressively larger raker depth might make too agressive for a square filed chain unless it was a pretty large cc saw. I guess the thought is as the cutter wears back it gets narrower and not as tall and to remove the same amount of wood can handle a higher angle of attack to cut the narrower but deeper chip.
... I would probably throw the chain away but I am trying to clean up a mile of fence line and I'm cutting small trees, brush (prickly ash, thorn apple, etc), fence wire and dirt and... you name it crap. Hopefully the chain will last long enough to get through with this ugly job.
