A long mishnah… specifically on how grain-offerings can be brought with invalidating intent, and how that will make the offerings “pigul.” Yet, sometimes, the offering will be invalid, but the punishment for that would not be “karet” (and other times, it would be karet). Plus, the measure of an olive’s worth, and the impact of that size portion. Also, the distinction between a sinner’s grain-offering, in that the frankincense is not offered, and the burden of violation to the extent of pigul is slightly harder. Plus, again, whether a half-olive measure of eating and a half-olive measure of burning can combine to make a full-olive measure of violation (spoiler: the answer is no).
