Analyse your numbers again:
GZIP only: 19758 / 62885 = 0.314... = 69% improvement.
YUI+GZIP: 10818 / 62885 = 0.172... = 83% improvement.
Total improvement YUI+GZIP gives over GZIP only: 83 - 69 = 14%
Okay, so YUI gives a 14% improvement, which is more than my
guesstimate of 3%. Fine. But is it worth it? My opinion is still no
due to the maintenance overhead.
