0.4 second Catch & Shoot

[chicodork]

By rule, a player can't catch and shoot with 0.3 seconds or less from an inbound pass. This obviously means you can catch and shoot with 0.4 seconds or more on the clock. Counting tenths of a second in your head is impossible so how quick do they have to shoot with 0.4 seconds? 0.6? 0.9?

In tonight's game, at the end of the first quarter, with 0.4 seconds on the clock and the ball in the frontcourt, Team A inbounds the ball, and the buzzer goes off as soon as she catches. She catches and makes the shot. My partner waves it off because of the buzzer, but everybody knew it went off too early. Game was 20-2, so coach put up a mild protest and we moved on.

I just want to make sure I have it correct next time.
