Yes, I have done the same for the reasons you stated.
I do something similar with my junior golfers. They walk and finish in 2:15-2:20.
If a USGA event and they mispronounce your name, they should double your winnings.
Also, if you have 5 minutes to look for a lost ball they PGA/USGA should have 10 minutes from the time of the infraction to reach a decision and notify the player.
