Just some thoughts (as a ref/coach/fan/parent) and not directed specifically at WKN, but wrestling fans as a whole:
There has always been reaction time, just not from rear standing. It disappeared for about a decade from rear standing, but existed everywhere else.
Kind of crazy, that we went from 2023 complaining about zero reaction time (rear standing) to complaining about too much reaction time in 2024.
I am not sure anything changed, other than the rear standing rule. However, when a ref blows a call, more people are going to see it than 20 years ago. Youtube, flo, Big 10, ESPN+, UFC Fight Pass, etc.
As an official, I always try to let positions play out and am very verbal about control. I'd rather be a little late on a takedown than early. Coaches don't always like it, but I am pretty up front with them.
(and I did see some bad calls regarding reaction time this year, but refs are probably no worse than they ever have been)
