Agreed it's not that bad if it was consistant. Even in your example lets looks at the C67S vs. That number should be 1X light by 2X long. The number acording to their own discription should be a C77 if you use the high numbers for short shank. Maybe I'm just easily confused. Like I said, I should just quit trying to understand and tell myself who cares, but then they come out with an Alpha explaination that doesn't explain and ... UG!
OK, I'll get over it now and move forward.
