Using that theory, a new automobile should be "broken in properly" by winding it up to max RPM and driven as fast as possible directly off the showroom floor until it loosens up. Or breaks.

However, I regularly test electronic components this way. If they are going to fail, they are likeliest to do so early in their life. If they succeed in passing a large number of cycles, they will probably last quite a while. We had a batch of relays that failed after a short stress test, but the next batch (probably from another production run) is still going strong a year later.

I take the "Captain Ron" approach. "If it going to break, it is going to break out there."
