Hi.
Concerning to CSS3 fonts tests in ring1, it seems there is a downloading time issue. It's frequently happen esp. mobile browser. "Custom font" and "Custom font distinguished from non-custom" tests probably expect 100ms as a font downloading time. but it seems it's quite short time for mobile devices. 4000ms is appropriate duration for this according to our lab test.
What do you think?
best regards,
wonsuk.
