If you have the ability to clear out or "reset" the STFT and LTFT you will see the change in the LTFT numbers to be more accurate, as it has "wiped out" the old STFT data that causes the LTFT numbers to be so skewed.

Not sure that's doable with a hand-held tuner, but that feature is available on software such as HP Tuners.
