Default Over shot card

Will A over shot card change the barrel pressure?

All other things being equal, I would think the pressures would be minimally higher due to the increased mass of the card

According to Precision, my roll crimped paper shells, with overshot card, were consistently lower than my same charged, folded crimp shells.
An overshot card, used as a filler, atop the shot, then fold crimped, may be infinitesimally higher than without the card. ( A bag of 500 over-shot cards might weigh a few ounces.)
