We wasted more time in the first half and there were only 3 minutes added to that, not so much in the second as half the team was already on a yellow.
Indeed. As I said in the match thread, with his "injury" and other lethargic play I thought Wes wasted at least five on his own
As to the OP - this is what happens when rules are actually applied. I guessed 9-10 but was not at all surprised at 12. Lots of subs, lots of "injuries", a goal, a lot of general fucking about, it adds up. Fast.
