The battery range displays an ESTIMATE. So after the car sat and had a chance to recalibrate, it determined that you may actually have a few more (or less) miles than it originally estimated.
How much can get put back on regen will vary from 100% on an empty battery going down a steep long hill to 2-3 miles. I can usually add about 5 miles on a mixed road 60 mile trip here in flatland Illinois, but that depends on your driving style as well.
