Wanted to bump this thread with my findings for MLB 14.
I did some testing of the injury slider for simmed games in franchise mode. Last year I found that Injuries at 10 produced the most realistic amount of days on the DL per team compared to the MLB average. People assume from all the pop-ups you get that it is extreme, but I found it is much more realistic than using Injuries 5, and still not quite enough to emulate the amount of injuries in real life but it is as close as you can get.
According to this page:
http://www.fangraphs.com/blogs/2010-...m-information/ and
http://www.fangraphs.com/blogs/2010-...position-data/ The average amount of DL days per team is 900-1000 days per season with about 3/4ths of that time going to Pitchers on the DL.
This was the results from setting my Injury slider to 10 and simulating a full season as the Mets:
Duda 2-3 Month 90
D Arnaud 1-2 Month 60
Torres few days 2
Niese 6 Month 180
Colon 1-2 Month 60
Young Jr Few Days 2
Young Jr 1 Week 7
LaGares few days 2
Davis few days 2
Teagarden 1-2 Month 60
Wright few days 2
Davis few days 2
Gee few days 2
Duda few days 2
Davis few days 2
Wright few days 2
Gee 3-4 weeks 28
Young Jr. 2-3 Months 90
Young 1-2 Month 60
Granderson few days 2
Duda 2-3 Weeks 21
about 678 days on the DL.
I recommend if you want the most realistic amount of injuries that when you simulate the CPU vs CPU games as well as any of your own that you set Injuries to 10. I have a slider file named 'Simulation' where I put everything at 5 except Injuries 10 that I load before simming, then if I play a game myself I load my offline settings beforehand.
As for what slider to use in-game during gameplay I haven't narrowed that down yet. I would like to see around 1 or 2 injuries per 7 games but I have to play more to see what Injury slider would get me that result. Right now I feel 5 is too low so I am testing 7.
