Unreadability is the primary information source for this method.

Considering stability is the name of the game:

1. If it’s changing quickly in the ones position because it’s not stable, that’s immediately apparent

2. If it’s changing quickly in the significant digits, specifically hundreds or tens position, that’s immediately apparent

Which is largely all the info a user cares about anyways. It gives them the three important states:

1. Stable

2. Mildly unstable

3. Severely unstable

That is, if the number is entirely unreadable with this strategy, it’s because the game is entirely unplayable.
