Default Mash stirring and HSA.

I will be a new AG brewer come this Sunday (weather permitting) and my question is:

How much stirring of the mash is too much?

Can over stirring of the mash contribute to HSA?

If the stirring is too vigorous (if possible) can this also be attribited to HSA?

I have read some conflicting info on this subject and need some clarification.

I believe that HSA is possible, but extremely rare. I have never known it to be casued by normal mash stirring.

Since I am new to this what is "normal mash stirring"?

5, 10, 15, minutes?

Vigorous, or just good stirring to mix everything?

I stir 5 min. or so after every water addition. I stir vigorously, but carefully. I try not to have bubbles in my mash, but I don't worry if I do. My best advice, short of actually being able to show you, is to stir as much as you need to, no harder than you need to, and then enjoy the beer you're making!

And Mr. Language Person asks...."isn't that spelled Occam?"

I give mine a good mix about every 15 mins. I keep it short to prevent any temp loss. Nor do I get carried away with how hard I do it, hot wort on the leg = Bad JuJu.

Have you ever tried not stirring every 15 min.? I used to do the same. Being the lazy type, I tried not stirring and found it made absolutely no difference to me.

Oh yeah, I've gotten caught up in doing something for the next step and didn't touch the mash for 45 mins, I still ended up at 80% eff. I think as long as you hit your temps right on, give it a good dough-in, and a really good stir right before you sparge and you'll do fine. That being said, i'll still stir mine about every 15 mins, I guess its more a habit at this point.

Quote:
From Wikipedia: Occam's razor or Ockham's razor, attributed to 14th-century English logician and Franciscan friar, William of Ockham is the principle that "entities should not be multiplied unnecessarily" or, popularly applied, "when you have two competing theories that make exactly the same predictions, the simpler one is the better."
I prefer to spell it after the dude it was named after, I don't understand why or how they added another "C" and removed the "K". I just like to give credit where credit is due, to each their own.
