I used to worry about this alot but found in practice it just dont matter. If your shooting dots you may hit the top of it instead of the center but on a deer its not mattered for me yet.
Someone said a pendulum works straight down. I cant see how thats possible. If its swinging you'ld be looking straight down at the top of it & if it didn't swing you'll be shooting high.

If your shooting even close to straight down you'll shoot high as theres no arrow drop at all. Think of the geometry involved.
