Gorst spent a lot of time getting the rack done and checking it himself so Gorst match was not not much of an issue. Check the Sossei, Oi and the match where Syklar said he thought his rack was good ...I can't remember if it was the first match of the day or the final. Anyway, I spoke to 3 people at my homeroom who were there and all said they thought Jayson was asking for too many re-racks - much more than other players. Also, I am not sure how you are quantifying a re-rack ... if someone had to re-rack the same game 3 times before it was acceptable was that 1 request or 3?
Beauty of streamed matches is you generally can vet the opinions of others against actual fact. So far in two of the matches you called out as examples, there is zero video evidence that backs it up. I watched the second set (final) between Shaw/Sky and didn't see any abuse of Sky with being asked to fix racks.
A "re-rack" is anytime a player (in this case Shaw) does not accept the rack as it is and the racker must doctor the rack in any fashion.
Sossei: Sossei had a hard time with the very first rack. Both he and Shaw attempted to get the rack solid. A third party wiped down the cloth in an effort to help with the racking. Eventually both were satisfied. The second rack Sossei wasn't happy with what he was giving Shaw, but Shaw accept it regardless. The rest of the set went without any complaints or finger pointing. So, again..., this Shaw complaint about racking pressure is without merit.
Final: There were 3 requests to fix the rack throughout the 25 games played. First by Sky in the 9th rack. The next 2 by Shaw, both in rack 13. Otherwise there were zero complaints or finger pointing. If anything the effort Shaw put forth ensuring solid racks for Sky during his comeback should be praised.
Oi: This was a hair more difficult as it wasn't the focus table on the stream, but I caught all of Oi's 8 racking efforts. He was asked to touch up racks 2, 4 and 5. Rack 2 he had to address 3 times. In each case Shaw pointed to the issue and there appeared to be no complaint by Oi once the flaw was shown. So this is the worst example by leaps and bounds and is only note worthy because of how inconsequential the other matches were in this regard.
So out of the Gorst, Sossei, Oi, and 2 sets with Sky. Shaw broke roughly 48 racks (not checking lags). Out of those 48, he asked 10 times for a rack to be cleaned up in 7 games. Out of all those, no one appeared to complain about what Shaw was pointing to as an issue. 20% could seem like a high number to some. However consider that the only person to have a consistent problem was Oi. Asking for a rack to be touched up once in a race to 9 (Gorst, Sky, Sossei <-no request actually made) and twice in a race to 13 (Sky and same rack) isn't sharking or placing undue pressure on anyone. The only outliner is Oi with 5 requests made to him.
Could it possibly be an issue with the effort Oi was making..? Is it possible that Shaw was in the right and Oi needed to put more effort into racking...? I think I hear the sky falling....lol
Is it possible there's an unfair bias against Shaw in the US and anti-fans are dreaming shit up...?
