Pinching kills speed in any boat. Cats go fast, so they get further when allowed their head. A boat will feel sweet when taken off the highest pointing angle. Go down to sweet and then as speed builds come up a little anda retain speed and sweet feeling.
THe guys I generally sail with can'r seem to understand that pointing at something doesn't actually get you there.
"I know I was pointing higher than you but you crossed in front of me....."

I think it is an uptight thhing. Pinchers just can't let go and trust the process. They sail moment by moment and don't look at the path.
