Skip strategy: Brush placement for draw weight--left hand delivery.

Regarding Figure A: If you are willing to accept the fact that every curler originates the rock line of sight delivery from a different point in the hack area, you can understand the need to place the brush differently for each curler.
You can also gain insight as to why it is necessary to place the brush differently for the in-turn and out-turn for the same curler when the true rock curl is the same for each turn.

The below chart, figure A, will indicate rock travel for a curler that "push" delivers the rock with the slider foot at the center of the rock -rock is to one side of body AND for the curler that delivers from under the nose (practically no-one) -the slider foot is to the right of the rock centerline.

If the curler uses the "lift" delivery and the rock crossing the body "decaying sine wave" slide to the brush line of sight, you will have to make your own adjustment. If the curler uses the "lift" with the "Y" slide out in which the body and rock come together (merge system) and try to find the brush line of sight, you will have to make an empirical adjustment.

Unless your sheet is tipped as was the ice in the 1999 Worlds finals, the actual in-turn/out-turn curl should be the same in the 4 foot--if the sheet wasn't herringbone shaved with a slanted shaver blade
with high "tip" angle?

The rule of thumb then is: subtract 2-3 inches for each foot of curl when placing the brush for the out-turn and you may need to add 1" per foot of curl for the in-turn IF the shooter delivers from under the nose and not parallel to the body centerline as do most current curlers.

How do you measure curl?
Curl measurement is usually estimated with the curl of the lead rocks being thrown in the "free guard zone."

Usually, a right hander throws an in-turn to the top 12 foot based upon the skip's best guess - usually brush placed at the 4 foot line. Say that the rock stopped on the centerline. We would assume the initial curl on new pebble was 2 feet. Or is it? Did your curler originate the rock from under his nose which could be 1 foot over from centerline and how many "turns" did the handle make?

The Book. The "book" is sold out and has placed on the web. It's free and good curling.

While I have your skip's reading attention, I would like to ask him/her why they squat when holding the target brush?

Three ideas enter my mind.

1. The skip is too tired or disinterested in the game?

2. The skip does not have any interest in my shot?

3. The skip does not want to give me the added advantage of the extra depth perception the upright/standing body has vs. the squat position thereby helping me make my shot.

So stand up with the broom in hand like you would stand at a urinal -ladies too!!

Timing from the hack is the key to weight control but consciously or subconsciously hitting the target brush/persons upright and square body can make that 2" difference in hitting the brush and or executing the right delivery weight. Remember, The Worlds was lost by 1/8" in the 6'th end, Canada vs. Scotland, so every fraction of an inch is critical in The Game of Curling.

As a skip, I squat AFTER the shooter releases his rock. I align my brush with the line of travel of the released rock (I may have to move sideways) to see the missed brush error so I can call brushing (for the inside shot only). When your brushers learn The New Millennium Brushing Technique, they will brush the "wide of the target brush" shot too!
