I'm just trying to work out where the refrigerant is during operation changes.

If it was R407C then internal fractionation would be a possibility. But with R410A there would be zero fractionation problems.
Yes they were and LG said all readings came back ok.

Thing is its not nessasarily after a defrost cycle this happens, could be the next on cycle that performance goes up or the next cycle performance may be poor.

Usually always good performance after a defrost cycle though.
