This is a site about Pro Yakyu (Japanese Baseball), not about who the next player to go over to MLB is. It's a community of Pro Yakyu fans who have come together to share their knowledge and opinions with the world. It's a place to follow teams and individuals playing baseball in Japan (and Asia), and to learn about Japanese (and Asian) culture through baseball.
It is my sincere hope that once you learn a bit about what we're about here that you will join the community of contributors.

I'm not a novice on the sport in Japan, by any means. I'm familiar with the nuances and how the game differs from that here in America. Over the past two years I have been working on perfecting a mathematical formula to determine how good a baseball team actually is. I've statistically analyzed every MLB team dating back to 1900 and found three categories to be the most closely correlated to winning: OPS, Run Differential, and WHIP. Using regression, I've developed a formula that actually correlates better to winning percentage than the Pythagorean Theorem.
The model: (.503+(OPS*.097)+(RDiff*.006)+(WHIP*-.053). | Link to read reasoning behind it.
I've used this formula to rank every club in MLB dating to 1900 and I want to do the same for Japan, so that's where I'm seeking some guidance from Japanese baseball experts (if you know statistics, that's even better).
Right now, to acquire data, I've been getting data from Baseball Reference, however, the process is tedious because I have to create a new Excel sheet for every season and league. By chance, do you have access to data in Excel format that would contain yearly team data for OPS, Run Differential, and WHIP? This would save significant time and I'm sure something exists that I'm just not aware of.
Also, I've completed the data looking just at the decade of 1950-1959 in the Pacific League and found the following results - knowing what you do about the history and greatest teams, would this list fit with what you would expect?
Top 5 PL between 1950 - 1959
1956 Nishitetsu Lions
1954 Nishitetsu Lions
1950 Mainichi Orions
1955 Nishitetsu Lions
1951 Nankai Hawks
Bottom 5 PL between 1950 - 1959
1957 Daiei Unions
1956 Takahashi Unions
1952 Kintetsu Pearls
1955 Tombo Unions
1958 Kintetsu Pearls
Lastly, plenty of books exists regarding the best MLB teams of all time, but do any exist about Japan's greatest clubs (in English or Japanese), are there any reputable articles out there, either in the Web, scholarly journals, or anything else that you can point me towards?
Thank you so much for your time. Any help or guidance would be great.
