Cards at Party versus Brick & Mortar

Not to sound conspiratorial, but having been to brick and mortars in AC, it is interesting how many straights/flushes/4 of a kinds/full houses/rivers occur on Party compared with brick and mortars. These are more rare at a B&M.

Does Party have its card generator independently reviewed (by a commission, accounting firm, whatever) to ensure there is no foul play? I feel somewhat secure going to a brick and mortar because the NJ Casino Commission is watching things, but as far as I know, no one is watching over Party.
