There's a simple solution to this: Someone who always plays at a very slow tempo, even when they're playing a singleton, should simply not enable auto-play if they don't want their opponents to be able to detect this.

We took pains to ensure that the auto-play is not instantaneous. It takes about a second, which we assume is comparable to how long most people take to play a singleton by hand.

We don't keep a record of each player's normal pace, so we can't match that. If they're normally very deliberate, then auto-play will stand out, so they should disable it.

The issue in this thread is that declarer "guessed" right because a slow defender enabled autoplay.

Even a deliberate player can probably manually play singletons very quickly by hand, so they can give UI to partner if they want to.
