Designer Project Properties

In the designer project properties window under the Project/General heading is a setting ‘Client Poll Rate’ and under the Client/Timing heading is a setting ‘Polling Base Rate’. What is the difference between the two?

The manual is very unclear on this.

The Polling Base Rate is for any polling SQL query that is set to Relative rate. It is a single setting that can be changed in one location. The Client Poll Rate is other information from the gateway.

More specifically, the client poll rate is the rate at which the client will poll for tag changes.
