Slow down randomly generated value
Is there a way to slow down a randomly generated expression value? I have added a simply random expression to my blur size that ranges between 6 and 8 pixels. As you know the value is recalculated every frame. Is there a way for me to recalc at a different rate? Thanks for your help.

I think this page is what you want. Dan introduces hold time to a random expression (with seed random, true):

He gives many variations, methinks one will do the trick. There are four page of randomness, a tour-de-force.

Also consider using wiggle() instead. If you want it to blur between 6 and 8, then set the blur value to 7, and then add this expression:
wiggle(1,1)
The first argument is the speed of the change, in this case: 1 time per second. The second argument is the amount of change, in this case: 1. So it will randomly raise or decrease up to 1 amount (maximum 8, minimum 6).

Thanks to both for your suggestions. i tried adding a wiggle and but was receiving errors. Perhaps my values were out of range. I will try this again. Thanks again.
