just my ramblings...
I would think that the gate to shifter over travels (X & Y) should be well known.
thus to tweak the linkage adjustment would be shove it into 2nd, adjust turnbuckle to get the expected "X", lock the turnbuckle, shove it into 3rd and if "Y" is less than expected, you have looseness that needs to be fixed.
anyone care to share their "X & Y"s
