Your observation/experience on your manual watch’s timing rate during its power reserve curve

Does your manual wind watch gain (run faster) as its mainspring "winds down" towards the [middle of its power reserve curve] and then runs slow (loses time over time) towards the end of its power reserve curve?

Just checking in on how your manual wound watch runs (fast or slow) over the course of its power reserve curve (from beginning, to middle, to the end of its PR).

Thanks for chiming in!
