In my city, I know the intersections by their conduciveness to trackstanding. There are some where I can instantly find the sweet spot, and others where there is no sweet spot to be found. Those that fall in the middle I'll take my chances depending on how I feel.
Anyway, the other day, I started to lose the trackstand, and instead of bailing, which often would lead to a fall, I decided to save it. It was shaky, and I was moving back and forth in quick jerky movements, but it was the first time I saved a failing trackstand. However, it definitely was not worth the effort. I should've just fallen.
