Offset keyframes randomly

Hi!

I have a comp with 256 different precomps (made another thread about this project a few days ago).
All of these comps needs to rotate on the y-axis to 180 degrees. The thing is I don't want them all to rotate at the same time, it is supposed to look random. What I have done is to animate the rotation on all of the precomps at the same time, and what I'm looking for is an expression that I could add that would offset these animations randomly by about 10 frames. I cannot offset the comps them self in time, since they all contains an animation that needs to be sync.

I think this should be quite simple, just a short expression on the rotation value?

Try this:

maxOffset = 10; // frames
seedRandom(index,true);
offset = framesToTime(random(maxOffset));
valueAtTime(time-offset)
