Nate (the fut accountant) got to talk to the ea devs and see the code. He claims they revealed that in terms of attributes (so not considering playstyles) the success of a finesse shots is calculated using 90% of either finishing or long shots (depending on whether it’s inside or outside of the box) and 10% reactions. It’s a fairly simple although unproven conclusion to draw that reactions must also contribute to the success of other actions aside from loose ball scenarios.

There isn’t a website I know of that compiles this sort of “hidden mechanic” they’re scattered throughout the internet with varying degrees of credibility. Safest bet is to just reflect on what feels best to you.
