We have seen where people writing on this forum live at 4500 or 5000' elevation. It is a tiny sample, but of the few, I've not seen hardly any reporting AMS.
(Only there was a recent rescue of someone at Trfrom a higher-elevation Colorado residence who needed a rescue from Trail Camp. The thing we don't know is how much time he spent in CA before Whitney. I suspect he spent some weeks and lost his acclimatization before hiking Whitney.)
Since the above study was Whitney hikers, very few were those who actually lived around 5000'. However, there is very little AMS reported in the Colorado 14ers, and most residents there live at that elevation.
Bottom line, I am sure your week at 7k will have a marked positive effect.
