I've noticed that we roll dice far more often in our "casual" non-recorded games than we do when recording our AP. And I think that plays heavily into the concept of Play As Performance. When recording we stay in character for longer periods of time and are more likely to move the plot along narratively. We're more concerned with character interactions and having a coherent plot. Rolling dice can interrupt that dialogue and we often find ourselves skipping it in favor of role playing it out.
In our non-recorded games we're more likely to go off on whatever weird side adventure catches our fancy or spend 45 minutes taking to the possible villian about Hot Potckets. There's still the performance aspect, but it's a performance for ourselves, without having to worry if an audience cares or could follow along. We feel like we can roll dice and "interrupt" the story/performance more frequently.
