All errors are random/probability based. It is just like prime/orthos giving an error in 45 minutes on first run, then not until 2-3 hours or in 20 minutes on the next with same settings.
I think 5 to 10 runs are great for quick adjustments, which is what I will use this program for primarily. And 20 runs (assuming setting 1) may prove you are within a notch or two of stability. From there, some will game/fold/etc as final test...others prime/orthos overnight...others 50+runs of this test.
In my post 206 in this thread...I tested at 1 notch vcore below stability, where orthos 10ffts and prime small ffts has failed at 8 and 10hrs. Intelburntest failed one 30 run at max and passed one. It made 2 errors in first 60 run, and 1 error in second 60 run but not until line 49, so may well pass a 60 run if ran enough times. Odds are also unlikely it would pass 2 60 runs (3 hours total) in a row and odds are it would fail the first run. But it is all probability of error over time.
