Yes, I know. The whispered "go" was 4-5 seconds after BR touched first.

Partner understands that LBR is nothing until pitcher catches and possesses the ball (and is off if she makes a play). I couldn't convince him to "turn on" LBR the moment BR touches first base on a walk though. If a runner is off at that moment, it's exactly like the pitcher catching the ball at that moment.
