Del, good to hear of fair success after shoulder surgery.

Can go either way. And as we age it seems recoveries (particularly from surgeries) seem to get tougher and tougher.

80% functionality and improving strength doesn't seem all that bad to me. Had a bunch of hip flexor muscles get torn up, decades ago, and it took far longer than that for ~95% recovery. And you're now able to do a range of lighter dumbbell exercises as well. Wonderful.

Hopefully it'll continue improving. "Spiders on the wall" ... "wax on/off" ... and all the rest.
