Swadesh list for proto indo-european and coefficient of relatedness

Given two Swadesh lists of two languages, we can calculate a "coefficient of relatedness" by counting the proportion of cognades. Given two languages, L1 and L2, let’s call C(L1,L2) to this coefficient, which will be a number between 0 and 1. Now, I was attempting to calculate C(PIE,L)* for every (or at least a bunch of representatives ones sampling every major branch) modern living indo-european language.

It is extremely tedious, but potentially doable with a computer, of course, but I was guessing that probably this is out there somewhere. Where could I find such an info?

Also, even if not all these numbers are available, I am very much interested in the following question: For which L’s is the the coefficient C(PIE,L) largest? And for which languages would it be smallest? I am not sure either what would be "large" and what would be "small" in this context, so perhaps someone could comment on that too.

(*Note: In this context, substitue "being cognades" for "the word in L descend from the word in PIE of the same sloth in the Swadesh list")
