JRutledge wroteWhat do you mean once for each team?
If I decide to give a warning (or two), never a given for me in any particular game, I'm not giving warnings for "touch" handchecking all night long.
JRutledge wroteWhere is this interpretation?
Technically, it isn't an interpretation.
It doesn't have to be because it's explicitly and clearly written right there in the rule language, no further interpretation is necessary.
10-7-12: The following acts constitute a foul when committed against a ball handler/dribbler.
a. Placing two hands on the player.
b. Placing an extended arm bar on the player.
c. Placing and keeping a hand on the player.
d. Contacting the player more than once with the same hand or alternating hands.
If it isn't illegal, it's legal.
10-7-12-D allows for a legal single "hot stove" touch.
One "hot stove" touch is legal (if it isn't illegal, it's legal).
A "more than once" hot stove touch is illegal handchecking.
