I think this term has been changed or used for more than the intended purpose it was originally used for. Was talking to my great uncle last night about our old trips down SC n NC years ago and other places. He says, "I always liked them slow starters because they finished strong." A buddy says," I like mines to start up early." They were speaking about 2 different things using same lingo. My buddy meant he likes his dog to appear turned on by 14-16 months. My uncle was talking about performance, start off slow, conserve energy, be smart while opponent running himself tired then the onslaught. See we have since changed that terminology to mean when a dog is on. He said we don't send boys to do men work. I don't care how you act at 6, 12 or 15 months. You still a boy, I only care that show me you're interested when your 22-24 months. Then I hope when it's time you start slow, don't let that adrenaline burn you out, slowly work your way in, be smart and methodical and when your opponent down, do work.
