Ubiquitin, I still don’t understand, but you might be making the same error as many others, that by definition, eating a k’zayis within k’dei achilas pras must be easy. What seems to be ignored is that our modern day matzah is much harder, and more difficult to chew and swallow, than bread, and the shiur of k’dei achilas pras is measured in bread.
ZD, those who have a hard time may indeed rely on the more lenient opinions, but you’re wrong for extending that to everyone.
