You got a poor sample. Just like sample variation in lens, Olympus tends to have sample variation in IBIS performance and you got a clunker. My E-PM2 however is quite good...just tested 1/125 on 60mm on my 40-150, no IBIS issues.

I don't think this is correct... no one really knows exactly what triggers the problem--maybe Olympus does but they're not telling us--so you don't know that you don't have the issue.

I think the IBIS problem is a design defect and not sample variation.

I think that the sensor being suspended by combination of magnetic fields and springs could potentially have mechanical or electromagnetic variances that can account for slight differences in IBIS behavior.  I also believe there is definitely a potential that hand holding shakes slightly differ from person to person as well but the issue here seems to be that 1/125 is always causing pretty large double image and not 25% of the time or 50% of the time but almost all the time.  If it was a random occurrence I would believe it to be more due to random handshaking movement.

It's been said you cannot 'wet' clean the sensors due to messing up the IS and alignment.  Thus the question is raised on whether or not sensors can be out of alignment due to all sorts of issues such as vibration during shipping, etc.  Wet cleaning to me does not seem like a hugely destructive force any more potentially dangerous than keeping your camera vibrating while in transport/shipping.
