Well, assuming good internet speed, good PC(for flash rendering) and playing on 1x speed. The biggest problem then is chase.

Specifically, the server doesn't wait very long, only about 1 or 2 second, before it consider the chase to be finished and proceed to the next action on the server side.

While on our end, chase chain takes quite a while to render out.

As a result, any mystery use before the first long chase of the round will be more or less as soon as you want. But after that, huge delays.
