Are there any sources that require, suggest, or recommend that one eat the largest opinion’s kezayis of matzah within the time span of the shortest opinion of kedei achilas peras? The reason I ask is because kedei achilas peras is the time it takes to eat multiple kezeisim, so the larger one’s kezayis, the longer one should have to eat it. (To get more technical- a peras is either 3 or 4 beitzahs, and kebeitzah either two or three zeisim- so at minimum, the time span of kedei achilas peras is the time it takes to 6 kezeisim).
