I looked myself and found some more info from the
AyuReady site.
On the New Year's special, AyuReady? reached its highest ever audience rating at 11.0%. The May 31st episode (AyuReady 34) had a rating of 10.8% so it did pretty well. nmskalmn informed me that they always put up the ratings on the AyuReady site, so you can check that out if you're interested.
