I'm hitting just one of them. At the beginning I tried to use the default settings (n_val = 3), then I started to create the bucket with n_val = 2. I've tested a lot of combinations to w, but I could not see any substantial improvement. If you have any suggestion, please, let me know. I can do any test.
