On the one hand it can be said that it is normal for it to descend to about 0 and slowly rise until normalized, this process can take 1 or 2 minutes
According to the mentioned data, if the pressure does not normalize, some reasons to review are
slow indoor fan speed
Serpentine dirty indoor unit
Dirty turbine
Dirty filters
System obstruction
Strangulation of lines
Badly open bearings
I would not go for the lack of compression since this generates the opposite effect
