No, i did not improve it for WAC. Actually, it is getting a bit worse with time.
I only use some of the more difficult WAC positions, to quickly check, if
anything got really wrong.

I don't know, if Steffen is reading this thread. I asked him the same question
by email once, and he told me that Hossa won't solve WAC 230. You can see
Hossa's performance on WAC on Steffen's site:

Is any of the commercial programs able to solve WAC 230?
