RE: Time to raise score to qualify for P&Y?
Personaly I see no need to change it. I'm not one to follow P&Y so I really don't care but the standards have been set a long time ago and should stay.
By the same theory you present for raising them what would you want to do if the herd was devastated by say CWD or something, lower them back down for a couple years. No it should just stay the same and all is covered.
