Thank you.
I experimented based on your description.
pspmastercomp classic release I noticed first, the Release time (the time until GR meter returns to 0 ) became long when the Classic button was turned ON.
In the case of this material, "Release Time 7500 second in Classic OFF" is about the same as "Release Time 450 second in Classic ON".
However, there is a difference in these two. It is how to move GR meter, or it is the acceleration of GR meter.
In the video, "GR meter of Classic OFF" is accelerating.
However, this is due to the appearance of the meter.
In fact, "GR Meter of Classic ON" is slowing down.
Is my recognition a correct answer?
