FACT: INTURN and OUTTURN Curls the Same actual amount but rocks stop at different spots: Assuming the ice is the same for each rock path.
WHY? IF -- Each curler hits the brush target with the same weight and turns applied.
1. The ice has the same curl for each rock path.
2. Each rock curls the same (identical running surfaces).
3. Each rock rotates precisely the same at release.
4. Each rock is CLEANED in the same manner.
5. Each rock is pushed with same force. Note: The Blue rock traveled the same exact distance but fell short of Red position. (The Blue rock must have more push force to travel the same distance relative to the brush.)
    The above picture reveals the reason why an inturn will bury 3-6" more than outturn for the same shot.
    If you have a leftee on your team, you now know how to use his (inturn) delivery source to your advantage.
    A leftee can "get to"  the rightee outturn more easily and IF Jeff Stoughton could throw left handed and right handed, he would have had an "open" hit shot in the 1999 Worlds, 6'th end instead of a "hard to see" outturn which he missed and gave a steal of 3 to lose the game to Hammy Macmillan of Scotland!!
    The skip must adjust the brush target by 2" per foot of curl for a the rightee outturn.
    If you recall, at the Brier and Hearts, when Ray Turnbull "Reads the Ice," the curl around the center is shown as 4' and the outturn from out to in is 3-6". The actual curl is the same because the ice is the same BUT the source angle causes the rock to travel out further with farther to come back; hence, the curl "appears" smaller and the actual result is short and wide for the same delivery force and line.
    Again, this is the reason the skip must move the brush in 2" per foot of curl to get the same result for the outturn as for the inturn shot. A skip that can throw left handed and right handed has a tremendous advantage as long as the 2 hack system remains.
    Having learned the two handed delivery, it took me 2 weeks to wean myself from the right handed delivery to the EITHER inturn only delivery. After the change, I threw 3 100% games in the first month! No longer can any rock be hidden from my leftee inturn or the rightee inturn. It's just a matter of physics.
