Hey, just to let you know. Your OBP formula for the ratings input is off. Hits shouldn't be in the denominator.

I've now seen this. The formula was correct for the top half but incorrect for the bottom. It's now fixed.

-Durability calculation for position players now uses a scale close to what appears to be used by the devs.

I'm curious how this is calculated. For example Evoaldi, Miami pitcher with 106 innings in MLB, all in 2013 or Jose Fernandez with 172 innings. I'm guessing these guys get a durability penalty to distinguish them from more established players.

Fore regular starters (position players), it's essentially GP/1.64 (3 year weighted average). For reserves, I'm not exactly sure what they're doing, but they're scaling them so as to not penalize them too severely for not playing every day.

I'm not too sure on the pitching side, but I believe they may be looking at time spent on the DL as a factor. I only examined a few players, and since I couldn't find a site that had DL time in a format that was easy to use, I kind of gave up on it.

I don't really like the durability rating because it attempts to do two things at once. It covers player fatigue and injuries as well. Now, while it's true that a fatigued player might be more injury prone this isn't necessarily the case. On the flip side, there are guys who are in tip-top shape but are very injury prone. It's impossible to create these player types with one rating.

Fangraphs might help.

Click on 2013 and you get this:

Total days on the DL for each player in MLB.

Your other information is very interesting. For "weighted 3 year average" does the most recent year get more importance? For example to say with the Marlins Hechavarria played 148 games in 2013 but with 189 games over 3 years/1.64 he rolls out a durability of 38 unless they give more weight to a solid 148 games in 2013.

I understand what you are saying about their durability being a combination of injury and fatigue but I believe there is a reason. They are trying to keep injury prone players and young players with a small sample size from getting inordinate playing time and in the process rewarding those players with a track record of being durable. A guy like Yelich who hit .362 vs rhp won't be able to play more than 3 or 4 days a week due to fatigue. Any more than that and he risks injury. If I calculated his durability correctly he will get a 12.

My bad, the durability rating takes only the previous season's total. So, for example, Joey Votto played 111 games last year, making his durability rating 111/1.64 = 67.8. On the default roster, he has a rating of 68.

I did this calculation with about 20 or so regular starters and it worked out on the nose every time.

As I said before, with non-starters this doesn't necessarily apply.

For other statistics, the "weighted average" is (2012 stat * .5) + (2011 stat *.25) + (2010 stat *.25).

For guys who have only two seasons to draw from, it looks like they use a 50-50 average. If a guy has only one season, they use that. However, there are more anomalies and evidence of adjustments made to these players.

That's interesting, thanks.

Any chance you could put this online somewhere, like Google Drive, so that people can view it and use it online?

I can check into it. Never used Google Drive and not familiar with it.

Just uploaded version 1.2 which adds full splits. I'm attaching it to the first post in the thread.

Maybe I missed it but is there a way to import stats? or do you manually add the stats?

Stats have to be manually entered as of right now. Currently I'm trying to touch things up and create an export function that will create a roster with ratings for each team on a separate worksheet.

When that's done I might look into importing data from the web. I have no experience doing that in excel, though.

Would be a nice project, doing 25 players for EACH team...God Bless someone who has the time, but it would be NICE!

Can't wait to check this out when I get home. In the meantime, are you using any formulae for pitcher movement? I have been looking for a while.

Thank you in advance

If you go to a certain player's Tabular Data page on Brooks Baseball, it will give you the Z-Score for the movements of all of his pitches. I've been multiplying those by 49/3 and adding 50. So 50+(49/3)x where x is movement.

Re: New Sim Engine-Based Ratings Calculator Available (Download attached)

Pitch rating calculations is something I'd like to see included in the future. But I know so little about it I can't do it justice at this point.

tbucs have you tried looking at those Z-scores and correlating them to the actual pitch ratings found in the game? That's how I formed the tables for the pitcher side which I just redid.

Also, the new player search function may be helpful, because you can sort by pitch ratings. This would be helpful in getting ranges and averages for each pitch. The search feature is pretty nice, but it doesn't seem to be working properly 100% of the time, unless I'm doing something wrong.

Just an update currently I'm rescaling the hitting tables in accordance with what I'm seeing in the new version's sim engine. They're mostly the same, but enough of a change that an adjustment is warranted.
