Yes, read the same article. My guess is that the "expert" reply to the question was by a power pilot who hasn't landed a glider. His answer only covered an asymmetric deployment of flaps as a low probability of occurrence (hence low risk), not the
My DG FM says to set flaps to L or +8 abreast touchdown point on downwind. That's what I do, and then don't touch them again until stopped.
Did the same with my ASH 26E, except after landing, going to negative flaps for rollout control. That isn't necessary on the DG, so the flaps stay at +8 or L.
This lessens the workload during that critical phase of landing. After turning final, stick, rudder, air brakes are all that are necessary to get to aim point.

I have just read this article:I have no problem adjusting the flaps in the pattern. You do need to be cognizant of how your glider behaves by trying it (frequently, to refresh memory) at altitude.

I know it's about power airplanes, but I keep in mind an accident a
friend of mine had in an ASW20, stalling and spinning (survived with
serious injury) when extending the flaps in base to final turn. Ever
since I basically move the flaps to positive (Ventus B) only when I'm already on the final .
What is your experience/opinion?

What is your experience/opinion?
The early ASW20 had a different flap configuration than later models, my 20 had those beautiful Jesus flaps that gave the ship a bad nickname and eventually people came to respect those flaps, I wish my 27 had those flaps. The sister ship to mine wasWhat is your experience/opinion?
Start with the POH, not some poorly sourced article on the internet. Doubly so for an ASW-20. What's it say about landing flaps?

In the 20C (no Jesus flaps) and 27, it's best to wait until on final and the aim point is between your toes.
While the 27 does not have Jesus flaps, the maximum Landing flap speed is 80 kt. Landing flap, full spoiler and 70 kt brings you down at about a 14° slope as I saw in an IGC file.
