The other unknown SMART attribute 235 is still at 99/99/2, just as it was when the SSD was fresh out of the box.

Yesterday I noticed that the Avg MB/s field had been creeping down very slowly, in the 0.01 digit each day. It was still 113.13, but it seemed like the speed was decreasing. I think that ASU was averaging the speed from the last time the program was first started, which was many days ago. So after yesterday's data, I restarted ASU so that the average speed reported would only be for the last day. So today it read 111.30 MB/s. I'll keep restarting ASU after each day's data so that the average is only for the last day, and reporting the speed.
