Anyone have the more recent (post-Baseball Abstract) RC formulae? Dcarrano 1 July 2005 22:52 (UTC)

[edit] Article assumes knowledge

Reading this I don't know what 'H' and 'BB' stand for in the simple formula, it may be obivous to others, but not me. Please provide a link for these or a description like some of the others have.

Okay, I filled it in for myself, hopefully correctly, please confirm. WilliamKF 03:33, 7 February 2006 (UTC)

[edit] Confirm D ?

Can someone with a reference please confirm the formula for D please? I saw it elsewhere with the first term being HR not H with runners in scroring position. Thanks. WilliamKF 01:53, 13 March 2006 (UTC)

[edit] General Thoughts

It seems to me that neither of the problems mentioned in the "Problems with Runs Created" section are really problems because the formula is not designed to adjust for park or era.

However, there are other problems with Runs Created that are not mentioned: specifically that it doesn't value the homerun correctly. In a hypothetical league in which 10 runs are scored per inning , the difference between the value of a single and the value of a homerun is very small, because the batter who singles is very likely to score later in the inning.

Conversely, in a league in which almost no runs are scored per inning, the value of a homerun will be much larger than the value of a single because the batter who singles will be unlikely to score later in the inning and the batter who homers has already scored.

Although these two leagues do not exist in real life, less extreme versions certainly do. A game in which Pedro Martinez is pitching will have many fewer runs scored per inning than normal, and a game in which a terrible pitcher is pitching will have many more than normal. Runs Created treats each of these situations the same, and by doing so gives unrealistic results.

All of this is explained in the article "How Runs Are Really Created" which can be found at www.tangotiger.net. Chocaholic 04:23, 30 December 2006 (UTC)
