Take a card scraper that's been burnished on both sides of one edge. Hold it at 90º so that no edge makes contact and rub it on wood. You can rub all day and not generate much heat. Take a shaving and things get hot quickly.

That's because of visco-elastic compression ahead of the cutting edge. Heat is a major factor in visco-elastic compression. Metal, wood, and a lot of other solids react this way.

You can vary the amount of heat from visco-elastic compression by causing less wood deflection. That's one of the things missing in the Kato study, they ignore heat creation and opt for maximum deflection. I don't have to read books or articles about this, the more heat one generates through deflection and visco-elastic compression the shorter the edge life. It's not a straight line curve if graphed. A lot of experience tells me that changing from a 55º cutting angle to 60º generates more heat and a lot shorter edge life than when going from 50º to 55º.

I don't see where introducing more fiber deflection than necessary gains anything but you can lose a lot of edge life.
