I agree entirely with what you said. Of course the second calibration will hold longer - that's why I said "settle" = "stop rapidly degrading".My point was that the break-in period itself does NOT result in better performance. It's the recalibrating after the break-in period has degraded the performance that matters. And, I believe, the second calibration will result in no better picture than the first calibration. It will just hold longer, that's why it's recommended to wait the 100 hours.
No one here who advocates "breaking in" an SACD player as a means of improving its performance has ever suggested that it be recalibrated or adjusted in any way after the break in period. They simply suggest that the player will "magically" sound better all by itself. I don't buy this.
Follow Ups:
Since you agree that the "second calibration will hold longer", you agree that changes have occurred in the circuit during the first couple of hundred hours. Some will not agree with that.Anyway, the same "breaking in" applies to amps, and they need no calibration. Read the current tendency of reviewers to run any piece of equipment for a few days to a week or so before listening. Why would they bother?
I've recalibrated my SACD player a few times.

I disagree that these changes, occurring over the course of hundreds of hours, are likely to be an improvement.Why do reviewers run a piece of electronic equipment for a few days to a week before reviewing it? I suspect many just say they do to humor the true believers. A proper warm-up of an hour or two should be all that's necessary.
BTW: Why have you recalibrated your SACD player? Was it beginning to sound too good?
The reason why many components sound better after break-in is because the sound the designer intended to get out of the component is the sound after break-in. If the designer was trying to optimize the sound out of the box, then break-in could make it sound worse. But it would take extra effort to optimize the out of the box sound because the designer would have to keep rebuilding his prototypes with new parts all the time.Nevertheless, some components do sound worse after break-in. I have an inexpensive Panasonic F87 DVD-A player that sounded best new.
