The question we should ask now what are our preferences in grounding grids.
Mine is as direct to ground as possible with the least series impedance.

PS Has the gentleman trying out the 4cx250Bs in grounded grid (control grid 
connected to cathode) gotten any results?
I would like to know how it turned out.

RE:  What makes you think that the impedance between the grid and
common changes by a factor of 10:1 between 3.5 and 29.7 MHz?

That is a red herring.  Because the frequency ratio is about 10 to one
is the answer.
    This begs the question as to whether the impedance is enough to care
about, and cap or inductive,  or a series resonance.  Such wonderful
considerations are why we can discuss this matter after over 50 years.
