Comparing Mech To Hyd Cam Adv/.050” Durations

easiest way is to compare cams from vendors who use SAE method
.006 at the valve
That makes sense
but I haven't seen any commonly talked about cams spec'ed at .006 valve lift.
Why does this situation even exist?
I mean how hard would it be for a manufacturer to set up a test apparatus to give us an after-lashing spec?
Imagine how many converts to Solid FT there would be, once we knew what we were buying, compared to our current hydro.
