I had been trying to dial in my retraction settings. But I started with 0 retraction for a base level and increased the retraction distance by 3 mm all they way up to 25 mm retraction distance at a 26 mm/s retraction speed. The best one was 20 mm but even then also i am facing some issues. Can anyone tell what is the best one?

i found the right settings and was able to print the retraction test without any stringing.
