Everything I see in a quick search on google scholar says that healthy adults excrete extra and there is no established upper limit, this implies the upper limit is far enough away that almost no one ever hits it.
One data point: One banana contains 400+ mg of potassium and no one has had potassium related issues on a 30 bananas a day (12,000mg) diet.
no one has had potassium related issues on a 30 bananas a day (12,000mg) diet.
If I eat 1 banana per day, every day, I will get horrible leg cramps within a week. I really like bananas, so I’ve spent a lot of time testing this, although it’s hardly a double-blind high-sample-size study.
That’s surprising. Muscle cramps are a symptom of hypokalemia (low potassium). Hyperkalemia is usually asymptomatic until you have heart beat irregularities. Also, based on the renal excretion of potassium, I would expect it doesn’t accumulate much, and it would probably reach equilibrium in much less than a week, in a person with normal kidney function.

I’ve been conflating potassium and vitamin K, apparently.
Go me!
at least your caution didn’t go the other way!

To determine whether the problem with bananas is potassium, try other sources, eg, eat a potato every day. or KCl.
