Waht was the relationship of the foot to the pedal in this recommendation. It will make a big difference if the ball of the foot is on the pedal versus the rear of the foot or heel. Most modern discussions allow that there is definitely such a thing as having too small of a knee angle at max extension, with 25 degrees being a common minimum recommendation. Whether or thot that is "just a wee bit of flex" is beyond me. I'd prefer to work to the number or to use my elaborate method. And, it didn't feel "wee" to me when I was set up by this method.
The stress on knees from too little knee angle is in the back of the knee. For too much knee angle, it's the back of the kneecap, felt in the front of the knee.
