Consider your chop-in as "0". Then continue along with 1 from there. Use whatever arm feels good to you but I'm with BNR and use the same arm I chop in with.

Using different arms when switching from one count immediately to another was also a Fed mechanic clarification for the 04-05 season.

...and you end your count in the backcourt when ...?

I don't switch counts when I'm going from throw-in to 10 second count. I count my 10 second count with my outside arm. So sometimes I switch arms depending on where the throw-in is (determines what arm i'm counting with for throw-in) but I don't make sure it is switched.

Johnny, when do you end your 10-second count? (not being condescending). What do your instincts tell you?

Was this veteran partner an old school kind of guy?:D

I do all of my throw-in counts in the backcourt or for a throw-in which might be passed into the backcourt with my arm that will be away from the table as I turn and face downcourt. This allows me to switch arms and make my 10-second count towards the table and the benches.

So if I am tableside Trail with the table on my left as I face the basket of the team with the ball, I would do the throw-in count with my right arm and then the 10-second count with my left arm.

And, FWIW (not much), I do the opposite. My throw-in count is with the "outside" hand, and the other hand is the 10-second count. So, it might be toward the table or opposite the table. If there's no throw-in, then I count with the hand toward the table.

Count continues until the ball acquires frontcourt status for the team in control. So if the defense dislodges the ball but does not gain control, count continues until the defense gains control [in which case they are probably already in their frontcourt] or the offense gets the ball into their frontcourt; if the defense gains control and then loses control, a new 10-count is begun.

A pass in which the 10-count ends while the ball is in the air but "over the frontcourt itself" would still count as a violation because the ball maintains backcourt status until it touches the frontcourt.

For the dribbler coming from the backcourt to the frontcourt, the count continues until both the ball and the dribbler's two feet have acquired frontcourt status.

Did I miss anything?

I am with you all on this technique. I have practiced with the shot clock to get the timing down. Chop = 0, 1 & a 2, & a 3 etc. using the same hand I chopped in time.

Yup......
