Nothing arbitrary about the cutoff date I chose.
I chose that cutoff because, as I have posted before on several occasions, I really do believe that the Matchroom equipment and rules changes instituted in August 2022, especially the new break rule, hurt his chances a little. As has been observed by many on this forum, the formula for winning has changed, and the statistics show that there are fewer break and runs and that much more defense is being played in the Matchroom majors. Seeing more than a three pack from anybody at the Matchroom majors has become quite rare. The game has changed.
Shane's break may be the greatest weapon any player in the 9ball era has ever brought to the table, but with nine on the spot, a break box and tight pockets, he cannot dominate with his break in the manner he used to. He knows it, too, which is why he has refused to gamble using Matchroom break rules when asked. He's clearly still a superstar of the highest order and a living legend, but the Matchroom rules and equipment changes have made things a little harder for him. Go back to one on the spot, no break box and 41/4 inch pockets and Shane will win more titles. He remains a threat to win anything on pool's calendar, because he's still an absolutely phenomenal player.
That's just my opinion, and if you see it differently, I'm happy to debate the matter.
