I'm doing exactly the same thing. I have send friend requests that some have accepted.

No one figure it out!!  So, I'm pretty sure it's hard to figured it out for the average HS player (I already know that there is no statistical significance to say something) .

Anyway, mho is that an achievement must be achievable, maybe I'm wrong.

In my POV if you try to get it again and again, you should get closer of getting it, either because practice has improved your skill related to achieving it, or because of the fact of learning about the task you are doing. Obviously this is not the case.
