When you create new profiles or edit already existing profiles, those will show in the contributions totals on your profile. Your G2G activity will accumulate here.
However when you answer a G2G post that has a link to a profile that is being discussed, those often do get listed as a contribution. Have no explanation how it all works, just my observation from seeing "you answered a question" popping up on my contributions list and presume a point was also added to my total.
