Plowing your driveway in the middle of a blizzard is like trying to fix an inner ear

problem before the cause of the inner ear problem has stabilized.  A person who can't stand having snow on their driveway must wait until the snow stops before plowing or shoveling their driveway to yield lasting results.  Trying to fix an inner ear problem, like BPPV, before the cause of the BPPV has stabilized is similar.  You can do repositioning maneuvers all day long, but if the calcium crystals are still in the process of dumping out, the repositioning attempt will likely only provide temporary relief.  I have learned that treating acute BPPV is not the same as treating chronic BPPV.  Sometimes, an inner ear needs time after the calcium crystals have fallen out before repositioning is effective.  On the other hand, I have also noticed repositioning within hours of an individual becoming aware of their BPPV has also been effective.  Different people have different types of BPPV.
