Thermoking Magnum Plus VS Carrier Primeline

Hi mates,
I have a question, im wondering why in Frozen mode for me Thermoking is the fastest to in-range. During Frozen the supply temp dive almost -10C below setpoint, maybe for me the reason why it is the fastest. But in terms of Chill mode a see a different story because Thermoking is the slowest to make the return temp to in-range with setpoint. On the other side, Carrier Primeline is the slowest to in-range during Frozen, while in Chill its the fastest. Im am taking here with hot cargo. Does my observation is right or wrong? And if right, what is the reason?

So the thermo king goes way beyond set point?

Only during temp pulldown for frozen mode, but during chill the supply temp stay with the setpoint and does go down below that is why maybe it slow.

Look in the transport section on this forum there is a guy reefer mechanic sure he will advise you.
