@dyunov What's Dischinger's result you're referring to? (maybe you have it in a separate issue but we could use the reference here.) Is it a result that establishes symmetr of the π-regular condition?
@rschwiebert Yes, exactly that (under the definition "chains of form $Ra \supset Ra^2 \supset Ra^3 \supset \ldots$ stabilize").
Edit. There's a confusion in terminology, some authors call it strongly $\pi$-regular and others just $\pi$-regular like Rowen. In DaRT it's strongly $\pi$-regular.
