I am always reading something, particularly about rod building. I have seen the term RDA being used. For example; RDA = xxxgrams. I assume intrinsic power was what was meant. I do not remember seeing RDA in any of the CCS articles. Where did this term originate?

After the CCS was unveiled, the second article ("The Big Picture") appeared and detailed how to measure portions of a rod, rather than its entire length. Another rod builder took this idea and knocked off the CCS and called "his" measurement system the RDA. Just a copy-cat system.

Thanks. Knew I would get an answer here.

But, what’s the point? I’m guessing this knock off system produces different numbers. Why would anybody want multiple systems, producing different results, for this?

Rather defeats the point, does it not?

Some people seemed to be jealous that Dr. Hanneman developed a system that they didn't. So you take his, which was designed by great effort and research, to be not only accurate but simple, and put your own spin on it in order to gain some sort of notoriety or something, all the while addressing what you somehow think are shortcomings. The great flaw in the "RDA" or whatever you want to call it, is that it did not include a consistent point of measurement which had to be based on a percentage of blank length in every aspect (just like the deflection distance). Needless to say, Dr. Hanneman was/is a much sharper cookie than the guy who knocked off his system was. If the "inventor" of the knock-off system was smarter or had a better system, where was it all these years prior to the CCS?
