When the cabin is heating up, CCM directs most of the flow to the legs. Can you confirm that the air flow is still weak at legs level?

This flow is okay during warming up. It is mainly the dash vents that have a minimal flow.

I am driving around without the panels left and right of the console and the heater core is very hot on both driver and passenger side when touching.

Also forgot to mention, according to Vida, the cabin temperature and evaporator core temperature should have the same temperature readout. Initially during warm they do, the other picture from my previous post shows 26 /24 degrees C. In addition it felt for sure not lake ~90 F inside the car.

If you switch to manual mode, crank up the temp to max and select only central vents, does it blow a lot of hot air through the vents?

Blow some compressed air through the vents on the CCM. Or take it out and clean the temperature sensor.
