41CL/Time Module "Correct" doesn't?

Not sure if it helps, but over several years of correction, my AF settled down at around 12.7 (but possibly minus! it was a long while ago).

I don't think you should expect much change over such a short period of time -- indeed frequent correction, with its inherrent residual error can result in poor AF and timekeeping. In my experience and recollection, the interval for correcting was never more than once a month and often several months. It might even recommend such a frequency in the manual.

If you chose to keep DST, you'd need to remember not to allow that to slip into the equation, either use local time consistently or use UT consistently, making any systematic hour correction with T+X (again my recollection is hazy).
