Enable Expert Entry

Hello:

I look at peoplebooks on this and I am concerned it will cause issues if used.  Can someone confirm or deny this?

From Peoplebooks:

Select to specify that some users, such as expert or power users, can defer all processing of the data that they enter. This selection enables users to reduce the number of trips to the server for data processing, regardless of how the developer set field deferred or interactive processing. You enable this option in a component in Application Designer, and you specify which users have this option using the Enable Expert Entry check box.

Deselect this check box to prevent a user from specifying deferred processing
