Not all 2030 was born equal. Reynolds 'A' Quality was butted. It was 2030 drawn tubing. Holdsworth made their Freddie Grubbs of two different tube-sets; 531 (straight-guage) and 'A' Quality (on the less-expensive bikes). My 22 1/2" frame made of 'A' Quality is about what one might expect as far as weight: 2185g for the frame and 810g for the fork. I am not ambitious enough to tear down the 531 DB Barnard and weigh it, but I will say that the ride is almost identical to the Grubb.
I personally feel that too much focus is given to 531 and not enough to the other offerings from the various companies that comprised Tube Investments. I think it is just a matter of production numbers/availability: It is hard to find bikes of Tru-Wel, 'A' Quality, 'AA Quality, A&P Kromo, etc

If you want highly accurate predictions, I question the need for that goal. For me while low weight feels nice when I lift the bike, it is not significant for my riding. I want to be able to trust that a double-butted frame is actually what it says, but a few once’s of frame is undetectable. I can detect the pedaling response much more than weight.
