At what point does the threat of constitutional convention typically get Congress to act?

Did you even read my post? Or are you agreeing with it in an odd way?

As to the balanced budget it would take time to build up to it or you would destroy the economy. But it is actually a good goal overall.

How would the massive groundswell of support needed for a constitutional convention happen without simply causing the defeat of the Congressmen who were opposing whatever its agenda is? It’s impossible for Congress to defy a 75% ultramajority of every state unless they are just disregarding the results of elections entirely, in which case circumstances in the U.S. must have changed so much that asking how political pressure would affect Congress is a meaningless question.

What I find entertaining is that of those backers, several are would-be presidential candidates. I think they might be surprised if in some bizarro world this thing came into effect and they were subsequently elected President, only to discover everything significant they want to accomplish is thwarted by the many states that won’t go along.

IOW States rights are fine. As long as only the right states get to exercise the right rights. For certain rightward-leaning definitions of right.

No doubt it would. There is a precedent. The consitutional convention of 1787 (?) was called not to write a new constitution, but to propose amendments to the original Articles of Confederation which were not working. For example, there was no taxing power; the Confederal government depended on assessments on the sovereign states which could not be forced to pay them and sometimes didn’t. So they called this convention which went way beyond its mandate.
