Now,that I have adjusted the cable to keep a little more tension on the derailer, it shifts a lot better. But still not like a good road bike derailer, but better then it did for sure. No kick back at all on the commute. I did run it up to 24.3 mph. on the way home at 12:00 am I run it at 20.9. Did another 6.81 miles on the bike for a total of 328.91 miles.
