3-Man Mechanics Help

[CDurham]

1) If you close down in the LEAD and begin to rotate, I am assuming you finish the rotation even if the ball is swung to the opposite side?

2) Who chops the clock in to start the game. Table side or opposite table side official?

3) If I have a closely guarded count in my area and it progresses to the TRAIL do I still continue the count? If it is stopped, would I give responsibility to them?

Thanks everybody!
