Title: RBI Editing formulas
Post by: Suckerpunch on 02/15/08, 10:41:19 AM
Are there any proven formulas out there for determining power and contact numbers when editing RBI?

I don't think anyone has proven anything.  Many people have used a bunch of different yet probably similar methods/formulas to figure what to use when they make a ROM.

Stock has a formula that he used for his latest fantasy league, although I don't know any specifics.  About my only complaint was that contact ratings seemed much higher, in general, than in the original game, but that may be by design.

On the rare occasions I put together ROMs, I use the original programmers' method - it's mostly subjective, based on a combination of stats and what I know of the player.

There are no stat-based formulas for pitchers, that I'm aware of.

Thanks.  I'm working on a 2007 playoff and all-star rom and will probably just use the subjective method based on stats.  I've got all the players and stats imputed, just need to add their ratings.

I created roms for the 1966 American and National leagues using very basic formulas.

For contact I used a chart that looked something like this:
.250 avg - 26 rating
.253 avg - 25 rating
.256 avg - 24 rating
.259 avg - 23 rating
.262 avg - 22 rating
.265 avg - 21 rating
and so on...

Once I got into the .300s the avg increments were larger.

For power I used home runs per at bat with a similar chart.

For speed I used my limited knowledge of the players of the era and stolen base numbers to subjectively assign ratings.

For stamina I used innings per game which resulted in much more stamina for starters than the default RBI pitchers.

For pitch speed I used K/9 with a rating chart.  Not a very accurate way of doing this but I had to use what was available.

I subjectively rated the pitchers on curve and drop.

If anyone is interested I will post the actual charts/formulas I used.

Neyer's book was a great source that I used for pitcher's ratings.

Pitchers are usually completely subjective when I do it, but when I did a draft of all current players from a site off here, I made an excel spread sheet so that if I put in their AVG, OPS, AB, and HR for this season and then the previous 3, it'd spit out a contact (AVG based) and a power rating (based on HR/AB and OPS, gotta give something to guys who get on base a lot) that was weighted 60% toward last year and 40% toward the previous three years, with some adjustments for players who hadn't played all year in any of the last 4 years, due to injuries or being a rookie or anything. Speed was subjective as well.

I'm interested in hearing stock's formula, I may use his stats for an all time roster I'm making for a mod...

If anyone is interested, I finished my RBI 2007 playoff rom which is located in Nightwulf's RBI editor under the name 2007playoffsAllStar.  I'm pretty happy with the batter ratings but if anyone has any input on the pitchers, I would like to here it.  I went purely off of their pitching stats because I have little knowledge of who throws a good curve, sinker, fastball, etc. so any help here would be appreciated.

For speed, I use 0.5 * SB + 3B + 118.  I manually adjust so that the max is never more than 160.  Seems to give a reasonably good result.

If you applied this to the basic RBI teams (1986, I believe) here's the speed numbers for the Angels (actual RBI vs formula), as an example.


-----------Actual---My Formula
Pettis-----140-----147
Dcincs-----124-----122
Joynr-----130-----124
Jacksn-----128-----121
Dwning----124-----124
Grich-------124-----119
Schfld------130-----136
Boone-----120-----121

I have to think a formula that uses SBs would be much better.  You have someone known for being slow as molasses (Downing) faster than one of the better baserunners of his generation (Pettis).  The leaders in Doubles are rarely have any correlation to speed so use SBs and 3Bs to figure out.

OOPS, my bad.

Correct formula is 0.5 * SB + 3B.

Using Stolen bases, not doubles.  Damn fingers can't type today <grin>.  Doubles, you are right, makes no sense, as lots of slow power hitters get lots of doubles.  Stolen bases and triples though are mostly pure speed.  Mostly.  I fixed it in the original post, thanks for catching it.

Then your math or data is bad, based on your formula for 1986, Pettis should be 147 and Downing should be 124

Wow.  I need to start drinking a lot more coffee.  One cell error in my excel spreadsheet threw everything to $hit.  Grin.

Math error.  Fixed in original post.

Thanks.

That's a pretty good formula - looks like it turns out pretty well.

The RBI teams are from both '86 and '87 (mostly) - the Angels, Red Sox, Astros, and Mets are '86, and everyone else, including the all stars, is '87.  Armas, Reggie, and Burks are pulled from other years as well.

Yeah, looks good now
