Is there a good source for the Kanto saga's viewership ratings in Japan?

Just something I was curious about. I know we have info stating the racing episode had the most viewership of any Pokemon episode ever at 18.6 percent, but do we numbers on the rest of the series in it's most popular iteration?

The book Pokémon Story gives a pretty good overview:

The TV ratings for the show's initial April 1st, 1997 broadcast was 10.2%. It hovered around 10% throughout the rest of the month and then went up to 12% in May and 14% in June. In September, after summer vacation had finished, the show was regularly getting between 14% and 15% in the ratings. In October those numbers went up to 15 ~ 17%, and every episode that aired in the month of November achieved at least a 17%. The November 11th broadcast of Episode 33, "The Flaming Pokémon Race," earned the show its highest TV ratings to date with a whopping 18.6%. In that week's episode, the story revolved around Satoshi and his friends meeting the Laramie family, a group of Pokémon ranchers who work on a Safari Land / Pokémon sanctuary on the outskirts of Sekichiku City. Ratings fell a little bit to around 16% the following week, but then the week after that the show bounced back to earn a solid 17.7% rating. The show's average ratings of 17% continued into December, and just about everyone assumed the Pokémon animated series was going to be heading into the new year triumphant, celebrating its status as one of the new powerhouses of Japanese animation.

In the real-world Kanto region of Japan, the (Porygon)episode received a 16.5% TV rating.

From there, we can predict that close to half the children in TV-Tokyo stations' main viewing areas of Hokkaido, Tokyo, Aichi, Osaka, Okayama, Kagawa, Fukuoka, and Saga -- all of which aired Pokémon at the same time – watched “Cyber Soldier Porygon” that night. And according to the investigation conducted by the TV-Tokyo Planning and Research Office, while the age ranges of the children were limited to elementary school kids, 1 million 650 thousand children between the ages of 4 and 12 were watching in the Kanto region, while 3 million 450 thousand children were watching nationwide.

That's neat. I'm actually kind of surprised ratings started that low. I figured they would be a bit higher coming from the success of the Red and Green games.
