I stir about 3 times during an average mash, and more if I am not getting my conversion efficiency to about 96-97%. I find you can lose a large amount of conversion efficiency and therefore gravity points by allowing the mash to sit statically. It could be system specific, but I know how my brewery works. Before I paid attention to my efficiencies I didn't know about that and didn't stir as much.
How do you track conversion efficiency? PM me if you dont want to highjack the thread.

Check out this page:

Here is the spreadsheet I use for my brewdays:

I love using this sheet. It allows me to actively see how my mash and beer is reacting and has drastically improved my consistency and accuracy of brewing.

I use a RIMS system and you will need to stir during dough in. I stir once @ dough in, returning the mash through a simple CPVC manifold atop the grain bed and Batch sparging (with a mashout). I consistently get 90%+ eff. My efficiency is calculated by PROMASH.
