How to calculate cg_projectilenudge if I also use cl_timenudge?

[ping] + [negative timenudge] = [projectilenudge?]

or in numbers:

44 + (-8) = 36

quote from openarena wiki:

Note that it is possible to use cl_timenudge together with cg_projectilenudge, but calculating to which values you should set them together is not intuitive and therefor not very practical, and aiming and firing hitscan weapons becomes more difficult too because you have to take the cl_timenudge value into account and lead (or even trail) your targets.
