It was very helpful to see Jason Shaw in the interview after the match. This was asked of him and he addressed it well. He said that BOTH players agreed before the match to give each other the best rack possible and to rack according to the other person's request as far as placement etc... He said Mills was having trouble spotting the rack where Shaw wanted it, and was fine with the re racks. They BOTH wanted to be fair and Jason would have re racked as many times as Mills would have asked as well. I thought it was a clear answer and covered the agreement between the two players.
That said, I would prefer a template rack, but I do NOT believe Shaw was sharking based on that interview.
