You and a lot of other people who want to rationalize their expectation (demand?) to get the 83K miles are jumping to this conclusion without really knowing how the miles are posted for each item. It was explained very well a couple of pages back how the whole thing can be automated without much human intervention. The computer programs implementing all this logic are quite complicated and depending on what kind of bug is in the code, it can appear for different items at different times. But I guess you have to be a software programmer to understand that.

This does not mean that we know for sure that is what happened. But that is the most likely scenario. It will have to be a really stupid management decision to attract customers this way knowing very well that it can end up costing the company a lot more. So my SWAG (scientific wild a** guess, a term used by computer programmers) about the likelihood of what happened -
Software bug - 90%
Disgruntled employee - 9.999%
Management decision - < 0.001%
