Yeah, my wife pinches the top of my growing branch too. She says it helps it to slow it down so she can get rested.
Your right Unoit, its not really a pinch on the growing branch, more on the tip. And its really a "twist, turn, and tugand then threaten to snip it off" and Yes,it slows down my growth rate 5 time out of 5. But after you've been married ten years the honeymoon has got to end sometimes. I just hope that after I've been married as long as critter I don't have to hide in my grow room and pinch the end myself like he does.
