I was coming to ask how many times it goes out of sync, but seeing last post...I'll change my question.
With LFSRevLimiter, this depends on how many cores your processor has.
A friend of mine have just one and it stalls abou 50% of the times.
I had 2 cores, and normally it stalled 1 time each 2 or 3 laps.
Now, I have 3 cores and it stalled 2 times in 4 days.
Maybe you could find this information useful
