Amp draw from absorb to float

Hi,

Have BMV-712 and consistently shows Consumed AH approx -0.6 when transitioning from absorb to float. Next day charge accumulates another -0.6 to -1.2ah consumed in transition from absorb to float and so on every day. Have solar and is drawing approx 7ah overnight and will fully charge next day to 0ah consumed but again loses -0.6 in going into float. New to all this but still very confusing. Battery 200ah lithium.

Tail current 4%

Charge voltage 14.2.

Any help would be appreciated!

@Oz camper

Float voltage is lower voltage than absorption, so technically with voltage dropping it is 'consumed' to do so.
