Interesting data, and I don't doubt the integrity of your information, but it contradicts what I've heard from some other sources, that the #1 used .8/.5/.8 and the #2 used .9/.6/.9 for both top and seat tubes*. I find these figures plausible, since #2 bikes don't seem particularly flexy; and my #1-labeled Centurion Semi Pro doesn't have a crazy-thin top tube that I can deflect with a pinch between thumb and forefinger.

Maybe they lightened up their tubes (which is to say, shifted their numbering system) in 1981 - my experience is with 1976-1980 framesets.
