Charge Creep?

Been following all the posts about charge changes since V10. My charge also changed overnight after loading V10. Consistently full charge was 310 until the day after I loaded V10, now it's 308 to 309. Not a big deal compared to others, and yes I know it's just an estimate yadda yadda yadda.....its good, I'm learning all about battery capacity issues in these threads. But, I'm seeing another change:

When I set my charge limit, whether it's full charge or 80% roughly,....in the past the car would charge to my set point, lets say it ends at 250 mile estimate with slide bar set point. I leave my car plugged in my garage, it would stay at 250 for days if I didn't drive it. What happens now is, it reaches 250, then over time it creeps down.....might be 3-4 mile estimate lower by the time I drive it. I see this at full charge also....yesterday I charged full, .....it got up to 308-309, charger turns off, I go to drive 90min later, it's down to 307. It used to charge to 310 and stay there.

Not a big deal, just something I noticed that changed. Anyone else notice this?

FWIW I also had a VW eGolf, which had no battery management system and no vampire loss. No matter how long it sat, it would show same battery capacity. But each time you started it, it had forgotten everything: music stations, temperature settings... PITA. Worth $1 a day of electricity to have active BMS, settings memory, and connected car.

If I set my Tesla app notifications when charging is complete to "on", then I'll get notified several times a day that my charge is complete. Implying that the car is frequently topping up in order to keep its charge at the level I set. This also means that the range estimate must be varying a small amount to match the variation in charge. Assuming that the fallback before the charge starts is 1% SOC, then you'd expect your range estimate to vary +/- 3 miles.
