OK, I used Max's spreadsheet and calculated 1923 Ruth's OBP vs LHP which was 0.692 using Toady's post on how to do it. However, when I checked on DD using the card reader 1923 Ruth's OBP vs LHP it was 0.740 with no ballpark effects. Why is there a difference? Then I checked on DD Player Pool with Zero Park Effects for 1923 Ruth's OBP vs LHP which was 0.692. Does anyone know why is the DD card reader number is different at 0.740?

For some reason on DD "Ignore Park Effects" and "Zero Park Effects" mean different things. My guess is "Ignore" calculates for a neutral 10/10/10/10 park but I'm not certain. Could certainly use a better label.

With Petco it was 0.698. And there is a Zero Park effects at the bottom of the list and that was 0.692. There are no ballparks we use which have zero park effects which is what your spreadsheet is based on. And what are the columns W through AB on your spreadsheet?

I did it! All the OBP/SL/OPS numbers for all hitters vs. LHP and RHP. File at this link, feel free to download:

Go out to columns AL and beyond to see OBP/SL/OPS.

Thanks, Toady and Max!! AWESOME help!!

Yes Petco is one homer chance, not zero. Columns W-AB are BPSI, BPHR, and clutch, respectively. > # $ are the symbols the cards use for those events, good ones to know when you're examining a card.

Hack and Max, thanks so much for doing this! I've been making my own tweaks to my spreadsheet but was struggling with the right way to update it. This is a much better starting point, in terms of raw data. I promise I won't use any of these tools if I'm playing against either of you. <wink>

The other step would be to add BR (Batting Runs), RC/27 (Runs Created Per 27 Outs), and NERP (New Estimated Runs) vs. lefties and rightes. Anyone know those formulas or how to do this? Also, which ones do people prefer as most useful?

When you go onto to Diamond Dope, all of the formulas for RC/27, BR (BATTING RUNS) and NERP (New Estimated Runs Produced) are listed there if you scroll down to about the middle of the page. I prefer NERP although if you strictly use it on the lower budget leagues, your team's OBP will not be high enough to score the most runs, so you have to get some players with a high OBP, too. I also subtract the player's fielding and use it for the different ballparks on Diamond Dope.

TOMBAR3, I went through the same exercise and also had your same question. It seems clear that Diamond Dope considers "Ignore Park Effect" and 8/8/8/8 field. If you run a player through the Turner '05 field which is 8/8/8/8 you appear (unless I missed something) the same effect as "Ignore Park Effect")

That said I have a very basic question. I keep getting stumped by how to effectively incorporate the park effective into NERP if we are trying to recreate the Diamond Dope figures as a starting point. CAN SOMEONE SHOW ME THE WAY?

I assume that whatever the ballpark factors are, say 8/8/8/8 for example, one uses that figure dividend by 20 (the total number of chances) to show its effect. Thus an 8 factor in a ball park is effective 8/20 or 40%. This much is in the Diamond Dope info page.

Trying to us the MaxPower database which has an >L of 5 and a #L of 8, I am unsure where to go next. I presume that the single and homerun entries (using the lefty side for example purposes) of siL 13.50 and hrL8.3 need to be adjusted by the ball park effect but for the life of my I cannot figure out the correct factor to adjust these figures by.

Hoping someone can explain this to me...cheers.

1923 Ruth in an 8/8/8/8 park would be 13.5 + 5*8/20 = 15.5 singles vs lefties. 8.3 + 8*8/20 = 11.5 homers vs lefties.

Thanks Max much appreciated
