I'm surprised none of the pros (as far as I know) have attempted high runs during this down time. Now seems like the time to take on Schmidt's 626. Perhaps not enough pros have access to a table and/or they find the number too intimidating to try.
The pros don't earn their living at 14.1. Those having access to a table during the pandemic would surely opt to stay sharp at the games at which they can earn a living.
I can't imagine why anybody would focus on a big run at straight pool unless there was big money put up for a world record run.
