The 3x or 2x same order / numbers you mention. Those are called double prints. Perfectly normal practice.
I once explained how that works and some disagreed but they were not able to provide any other reasonable explanation.
That is a good catch BTW as part of my theory is based on double prints.
If some can do a run of the tape and PM how many 3x or 2x order / numbers we had today you can do your won calculations as the more I think about it the more sense it makes.
