Stats-Based CPU Sliders [MLB 17 Version]

[nomo17k]

This thread will be about yet another attempt at creating a slider set based on empirical data through running a bunch of CPU vs. CPU games, without any user input at all, just because there should still be a place for misanthropes. There was a similar thread last year.

The currently recommended "beta" set (a slight modification of the 5/16 & 5/14v2 sets).

Contact: 6
Power: 5
Timing: 4
Foul Frequency: 5
Solid Hit: 6
Starter Stamina: 7
Reliever Stamina: 7
Pitcher Control: 3
Pitcher Consistency: 4
Strike Frequency: 5
Manager Hook: 3
Pick Offs: 5 (untested)
Fastball Pitch Speed: 10
Offspeed Pitch Speed: 10
Fielding Error Infield: 8
Fielding Error Outfield: 5
Throwing Error Infield: 7
Throwing Error Outfield: 8
Fielder Run Speed: 3
Fielder Reaction: 5
Fielder Arm Strength Infield: 5
Fielder Arm Strength Outfield: 5
Baserunner Speed: 5
Baserunner Steal Ability: 7
Baserunner Steal Frequency: 5
Wind: 3
Injury Frequency: 5 (untested)
Trade Frequency: 5 (untested)

Notes on this set:

• Wild pitches are off, and only a patch can fix their inflation (keep fingers crossed)
• Batting average is about .005 down (plays at .250)
• HRs might be slightly inflated, but still within realistic level at 1.20 HRs per game per team (which is close to the current 2017 MLB average).

A slight variation of the beta slider set that would play just as well but with a different flavor:

Pitcher Control: 2
Pitcher Consistency: 5

with everything else the same. With this change, you will see slightly less walks but more hits, but the overall amount of offense should be similar. This set is roughly based on the 5/23 & 5/22 sets.


User Guide

These are adjustment made under the following philosophy for the game to play

• statistically as close as possible to the 2016 MLB averages
• aesthetically pleasing baseball for watch as CPU vs. CPU games

The assumption is that the slider set is used with a roster set with attribute distribution at the MLB level that are similar to the default SCEA roster that ships with the game. An example of such a roster set includes the very first release of OSFM.

Another place holder for now.

I've already gotten in the initial 75-game set with default sliders... Typically I've maxed out Pitch Speed sliders just because doing so makes the apparent pitch speed closer to real-life numbers, but I started out with everything at default this year, as maxing out Pitch Speed had (negative) side-effects on steal success rate in the last couple years.

Here are some notable points from all sliders at default, compared to real-life MLB numbers:

• Batting average is low (.238 vs. .255).
• BABIP is a bit low (.286 vs. .300) likely because the game produces more fly balls than ground balls.
• Swing & miss % is a bit higher (23.7% vs. 21.8%). This increases SO% (24.0% vs. 21.1%) and also contributes to the low batting average.
• Hitters do not chase chase as much (O-Swing % 27.3% vs. 30.3%), but this has been pretty constant the last couple years.
• HRs are a bit inflated (5.3 HR/BIP vs 4.6 HR/BIP).
• Doubles might be a little bit down still (6.1 2B/BIP vs. 6.8)... I think hits down the line do slice away in flight, but once they hit the ground they still don't roll away as much, so we s may be still missing the kind of doubles we often see down the line in real life.
• Wild pitches are quite high (0.95 per game vs. 0.37). Hit-by-pitch is also a little high, which might mean that pitchers are tuned to be wilder than in the past.
• Walks are a little down (BB% of 7.7% vs. 8.2%).
• Fielding errors are down (only about 1/3 of real-life numbers).
• There may be a slight tendency for early hook for starters "on average", but relievers appear to throw more innings.

As an MoM only guy I wait for these every year. Glad you are doing this again Nomo thank you. I ran approx 35 test games before I saw you were back. Main things that have stuck out to me are too many K's and WP's on default along with the low batting avg. Let me know if there are any side tests you need ran. I can get in 8-12/day as I work at home. Looking forward to these as always. My stats are not as in depth as yours (whos are lol). But I do keep up with R,H,E,2B,3B,HR,SB,CS,BB,K,WP,BA AVG

Great to have you back Nomo... I have "Borrowed" your Spreadsheet and have been Inputting stats as you do. If you need any help running games let me know!

Nomo you always bring great information every year to The Show Nation. Your efforts are very appreciated.

So far the worst problem I have seen is the crazy amount of Wild Pitches... The are having a big impact on the games, and by aces. have you see this aswell Nomo?

Excited for these!
