I agree its called less the higher you go, but I also think it happens less blatently the higher you go. I dont see V boys camp in the key the same way Fr Girls or Boys do. I like to think a part of that is because we whistle the 8 seconds in the key at the lower level. You do see people at higher levels push the envelope of being in there too long but it isnt as bad (in my humble opinion) at the higher levels. So I think you might have causation reversed on that one. It isnt that it is called less but is happening the same. I think it is happening less at those higher levels.
And I agree with you about call the 3 buy three rounds.
I dont think that means dont call it. It means lets not have cheesy technical 3 second calls. This is probably the best example of a violation NOT to call strictly by the book. See the "Tower Principle" post.
I think we are saying the same thing. But I still think there is a place for the call. Let it call itself.
