The browser share graph shows Safari is second only to Chrome globally. The page has a new item saying 'Safari accounted for over half of US mobile and tablet usage in March', so I don't understand your "relatively tiny market share" point.
the point is SPECIFICALLY about 'desktop+tablet+mobile' market share. not among mobile alone, because ad revenue is not factored on mobile views only as well.
you need to select the all browser from the dropdown.
