Just remember that spins in landing flap are prohibited - all explained in the manual.
I do not remember reading such in the '20 manual, and quick check on limitations and spin section does not mention this?
You are correct. The manual does say- “The ASW 20 spins easier and flatter with positive (down) flap settings (4+5) than with negative (up) flap settings (2+1). Therefore, setting the flaps in negative positions is a measure to prevent wing dropping and spins.”
The manual also says- “Recovery from spin can be easier achieved, if the flaps are set in a negative position.”

More importantly, with any flapped glider you must move the flaps to at least neutral to prevent exceeding positive flap limiting speeds during a spin recovery.
