I've played with him many times, he is quick to invite me to a Blitz Challenge game and before I realize it we are off to the putting challenge where he is awesome.
I think I have to make a rule with him that for every putting challenge we do we have to do 5 other challenges.
I think the 3rd ace in a row triples the score, I was able to get over 900k with two aces in a round on consecutive holes. If you figure an ace gives you 40k bonus points, he would have roughly 88k in regular points, 13k in green bonus, 128k in accuracy bonus, so that gives him 229k in regular, 200k in aces. That is 449k x 2 = 900k x 2 is 1.800 million.
That makes me think the first ace doubles your score and the next one doubles it again. We need different rules and a new category for Blitz putting.
