Yes. Smaller than 100-ton hulls were highly susceptible to misjump, increasingly with decreasing tonnage. But I do not recall if there was a formula in TNE FF&S.
I actually rather like this interpretation, as it gives a nod to CT/1e (LBB2'77 & LBB5'79 - haul the jump-torpedoes out of mothballs

), and it is touched on with the T5 Jump-readiness & Astrogation Jump mechanic as well.
