I do. Nothing about a budget precludes going over on an individual encounter. The 5 rules give a suggested(not hard set) budget for the adventuring day. That does not mean that a deadly encounter can't be over the threshold by some amount.Perhaps you don't understand what a budget is.
In 5e at least, it says you CAN build individual encounters with a budget, not that you have to. Even if you do use that budget, nothing says you can't budget enough to go over the deadly threshold. You're assuming things that 5.5e says that 5e does not, which is not to go over the amount given.
In fact, that's probably why 5.5e removed the word threshold. If they have included the word threshold and then said don't go over the specific number, it would have been contradicting itself.
