There's no hard and fast rule, but a basic rule of thumb is that it takes a thousand acres to justify owning a combine.

This isn't a hard and fast rule. It's been a rough rule of thumb for the last three years. For example, last year we had six teams of 12 players each. We had 52 residents and 20 non-residents.

A good rule of thumb

We don't have a hard and fast rule. When we have something serious like this, we suspended him until we knew all of the information. You have to use good judgment and common sense.

What we had in 16 acres, ... they have in three counties.

It’s hard to guess how smart the machines are, but a good rule of thumb is that they’re always smarter than you think.
