I have to mention the issue with "Ww" is only the right half size of the letter (the right "V" if you wish). The left size seems ok at all weight/sizes.
While we're all here, the letter "v" has similar issues as "w" at about the same weight/sizes.
Also, the letter "M" @ 700 @ 8px 10px 13px, and @ 300 @ 17px 18px looks weird. "M" is the mirror of "W", so probably the same bug.
