Thank you for confirming. That makes perfect sense.
I think I could live with that extra short device delay if that was the only issue. When I tail the log output and physically press the device, the button event appears after a couple hundred ms. That's within the wife-acceptance threshold 
But tacking on the extra variable ~200-800 of (apparent) hub processing delay to execute the rule action (i.e. adjust light level) is a disappointing result -- puts the overall execution time up around 1 second and puts me into wife-rejection territory 
My hope/assumption was that, with 100% local execution, Hubitat rule processing would be significantly faster than what I'm seeing. I'm wondering if I've misconfigured something on the hub?
