Wow! Terrific!
I talked with a Lifeline tech rep and he was surprised especially since I had a cheap single stage controller that was set too high at 13.7 volts.
I went over the numbers with the rep and then even did a second test. Without access to expensive testing equipment, there is some uncertainty in the testing but I came out better than predicted for new batteries so they cannot have deteriorated by much.
