Throttle won't stop throttling even after I've waited

I schedule regularly occurring posts, so I often bump into the throttle on posting too fast because frankly, setting up a weekly post from a template doesn't take very long.

The problem is that if I get a throttle error, I have to refresh the page to get it to stop erroring every time I resubmit, even if I've waited more than a minute or two and more than long enough that I'm not posting "too fast."

The error message needs to not permanently disable a post because redoing my entire post from scratch is no fun and surely not desired behavior.

Speaking of which, how long is the wait time? It seems to have gotten longer and I'm hitting the throttle far more often than I was before.
