On average, yes, but even at the top level, there are some big differences, and more than a few of the elite were, until the toughening of the break and the tightening of the pockets, able to win with lesser tactical skills because they broke and ran so often that tactical sequences were few and far between.
As Filler noted when interviewed during the UK Open, there is much more safety play in Matchroom events than ever before. AtLarge stats back that up, indicating that at least one safety was played in 55% of the racks on the stream table. That amount of defense is unheard of at the most elite level.
As noted, another huge change, statistically, is that the break is worth less than ever these days. Per AtLarge stats, the break and run rate on the stream table was just 19% and there was just one three pack for the length of the tournament. The power players, who, in days of yore, tended to sit their opponents down for long stretches, have to win with a different formula, and the price paid for any chinks in the tactical armor is greater than ever before.
Yes, going even tighter than last year was, to me, a very bad idea. As for the shot clock, the need for it could hardly be more obvious. I don't terribly care whether it is used in Stage 1 matches not streamed, but all other matches should have it. The absence of a shot clock devalues the professional pool product.
