you don't need to wait till you have a PK, simply, the idea is that if you, during the live match, do a change and you select another player, the engine should detect this movement, and concede a PK in your favour. Let's see.
In this case you, "maybe" and this can confirm ma theory, got a 2nd PK, cause after the 1st one you changed the player that missed the 1st, so, if my theory is right, was that action that did the 2nd PK possible.... so there's a relation...
