There are some players with low handicaps who rarely post scores. For them, the only reason to have a handicap is to qualify for tournament handicap cut-offs. To attempt to qualify for the US Amateur one needs an index of 2.4 or less. A true +1 doesn't really care whether his handicap is +1 or 2.1 since he virtually never plays anything but scratch.
Then there are players who selectively post in order to qualify. I know in talking to one such vanity handicapper, his motivation was to play qualifiers at relatively exclusive venues. He knew he did not belong. All he wanted was access to the qualifying sites. These players become painfully obvious once play begins. The USGA and various State organizations do try to limit these player's ability to enter their events (e.g. the USGA's "letter"). If the event is low enough on the totem pole, like the Michigan Senior Match Play Championship, the Association is generally fine with these "field fillers" paying $100+ to be eliminated before the Match Play stage.
I feel sorry for the good players paired with these poseurs.
You should really look at:
Rule 14, which tells you of a couple of ways you can mark your ball, including placing a club next to the ball.
Definition of Ball Marker, which talks about a number of different things with which you can mark the ball (including "an object made to be a ball marker")
The section in the Equipment Rules that @Missouri Swede quoted, which talks about when an object manufactured to be a ball marker becomes an alignment device.
The 2-inch limit applies only to objects intended to be a ball marker. The definition of "ball marker" allows you to use a "small piece of equipment". A tee may not be longer than 4 inches, so that's about the maximum size that would classify as a "small piece of equipment" in my interpretation.
My interpretation is that it's similar to cracking a whip. With pros, their hips start the transition/downswing with a rapid acceleration followed by a rapid deceleration. So the speed or "work" you're putting into the club is the results of the torso, arms, legs accelerating and decelerating. There is kind of a chain reaction from one body segment to the other, so you need the deceleration to provide the sequential transfer of energy.
Basically I "brake" or stabilize very well and will never be able to override it. I need more juice on the acceleration side. Honestly, I most likely should have started playing lefty, it's my faster side and I throw lefty.
This also makes sense for because I hit it the straightest when I feel like I'm swinging hard/fast. I get in trouble when I try to guide shots and then I can hit it all over the place.
