My tenure was randomly changed from 8 to 5 years. Then a few days later changed from 5 years to 7 years. I tried deleting the profile then recovering it but it didn't work. Anyone have any suggestions?
Tenure is based on the total years of Xbox LIVE Gold time completed. The clock stops when you go Silver/Free and Xbox LIVE Silver time does not add (or subtract) tenure. Tenure increases only when the year of Xbox LIVE Gold time ends. For your first
year of Xbox LIVE Gold you see '0'; it ticks over to '1' year of tenure when that year completes. If you've had Xbox LIVE Gold for 3 years and 6 months, you'll see a tenure of '3' next to your Gamertag.
There was a bug where Free (Silver) time was counted; that was recently fixed, so many folks now have less tenure than before.
