More on improper intent for time and improper intent for place - pigul is the issue with time, and one can get karet for it, while improper intent for place is not considered pigul, and karet isn't at stake, though the offering would be invalid. The issues kick in first and foremost if there were two different "avodot" - offerings - and the intents were then confused. Plus, several different approaches. Also, a question of what is really meant by an olive's worth (the measure of ke-zayit), in terms of timing and placement, that perhaps can be answered by the sages in Babylonia. Plus, complicating negative intent removes the offering from the concerns of pigul - or can do so.
