What is the algorithm used in A1 4.0 for determining values for priority and changefreq?
You can read how A1 software calculates importance of URLs:

Excellent - thanks for the quick and helpful reply!
By the way:
The Change frequency depends
last-modified
the revisit-after / revisit meta tag attribute
calculated page importance (used for priority)
To override Change frequency :
Switch of easy mode
Go through tabs: "Create sitemap" > "XML sitemap options"
Check "Override ChangeFreq".
Set dropdown to "*" value (as indicated in the tool tip, this removes the value)
