Achievement Percentage Error

Hey there,

That's an odd one! For achievement issues such as this, we recommend following the steps on our

Xbox Achievements Troubleshooting page. If the issue persists after waiting 72 hours, please be sure to submit a survey through the link at the bottom of that page so that data can be sent to the proper teams.

Thanks!

Achievement percentages are now back for me.

Beating the Gears 4 on Inconceivable has to be a crowning achievement for me. There's like a 0.01 achievement earned percentage for it.

Microsoft uses the achievements as the criteria for completion, not the gamerscore. If you look at your games played on xbox.com, there will be a completion bar for gamerscore, a completion bar for achievements (i.e 45/50) and a completion percentage. The
completion percentage is tied directly to the achievement completion bar.

For example, on Superman the Video game, I have 1000/1000, but I did not unlock the achievement for using a cheat code (it is a 0GS achievement). So, it says I have 17/18 achievements and only 94% completion.

May 01, 2015 - Looks like the achievement percentage corrected itself. Thanks.
