Adjustable rocker ratio

Now, after the confusion...
How did you determine actual ratio of those 273 rockers?
Or do we have a correct number here?(after reading Tony's math in the other thread, I'm guessing those things were NOT taken into account).
Which brings us back to "What is the true ratio of 273 rocker arms?"
Not knocking what you came up with 1970La, just really curious myself, too, as I just picked a set up myself for my 318 that I want to run with a solid lifter cam.
(Also, a big thanks to Tony for the good math)
