Power Smoothing on PowerPod

[TuRu00]

Hello!

I'd like to ask some questions about the power smoothing:

[*] How does it works? (Specially Dynamic value)
[*] What is the recommended value?
[*] Does it affect JUST on the transmission / communication channel (BLE or Ant+) or also in the power writing onto the PowerPod? Is the same value writed to .ibr / sent via ant+ every second?
[*] How does it affect to the Garmin readings? I notice some lag: if I stop pedaling, it still shows some power for a second, but when I open the .ibr it seems to be writed very accurate (no cadence, no power). Could be this? Garmin 520 and Smooting to Dynamic.

I would appreciate as much information as possible.

Thanks!!
