I noticed something about review audits:

When it's going to give me an audit, the page says, "Loading next item" for a long time (>4 seconds).

Otherwise, the wait time is <1 second.

#Edit - Confirmed by @Videonauth(1) & @Wilf(2):

1. No nothing new, I usually know as well by this that an audit is coming. Noticed that long time ago

2. I've noticed it occasionally previously
