When my FC is 30 and water temp is cold, 65-70F how valid are other tests?

as the title says my FC is 30 (started out high when I closed and still 30 when I opened a few days ago) and water temp is cold, 65-70F how valid are other tests?

My Ph is 7.2 to 6.8 after a few days of testing. High FC mean Ph test is not valid?
CYA is 50
TA is off the charts. last fall was in 80's now 300. Is the test valid?

I'm leaving the auto cover open for our 70's sunny days trying to burn off the FC and the SWG has not been turned on yet.
I assume without pool use and cool cloudy days it will take some time to get the FC back down below 10?

The only temperature-sensitive test is CYA. Let the test sample warm to room temperature before adding the reagent.

The pH test is not valid when the FC is above 10. Let your FC drop before making any pH adjustments.

pH and TA are affected by a closed cover since CO2 cannot off gas.

Leave your pool cover open for a while so your water chemistry can adjust.
