Can any roster gurus please share game rating’s conversion (baseball’s 20-80 scale)

[sandmac]

How are the true life player numbers calculated into MLB the Show player RATINGS?

What is the formula used when converting into the 20-80 scouting scale (which is industry standard to measure players skills.)?

In other words when we have a 99 in-game rating that would be a player with an 80 grade tool?

Are ratings based on the 2019 season or career?

THANK YOU!

I don't think SDS uses the 20-80 scale for rating players. Some roster makers might. Both SDS and the good roster makers on here usually use data to create the ratings.

I've created my own scale of attribute points to somewhat match up with the 20-80 scale. I'm really into prospects and I use FanGraphs to get their current value and future value on the 20-80 scale.

I've been going back and forth between these two. Just depends on how highly rated you want the prospects to be.

99-91=80
90-86=75
85-76=70
75-71=65
70-60=60
59-55=55
54-46=50
45-41=45
40-36=40
35-31=35
30-26=30
25-21=25
20-16=20

You need to create a spreadsheet with every MLB player in the game with their ratings for the skills in the 20-80 scale.

So here's an example of how I do this...50 is average, and in the past position players on the MLB roster in the Show was a 77 OVR and the STDEV is 7.6ish for overall rating.

Between a 40 and a 50 you need approximately 1 full standard deviation from 77. This would make a player rated a 40 FV a very nice potential of 69. Now going the other way a 60 FV prospect would be in the 85ish range. I can put all of my research in a doc if you want but it's from last year's game.

To determine these numbers in previous years, I've simmed 10 seasons with the default roster and painstakingly tracked what attribute ratings translated into what range of statistics. For example power averaged at about 59.

To translate to the 20-80, a 40 game power would equate to 45 in the Show, and a 60 would equate to 73. Then, if you want to be excruciatingly accurate, you need to pull the prospect's R/L splits to see how you'll adjust those up and down based on handedness.

How I'd do this is pull their overall numbers in the minors and boil it down to HR/PA for power. Then I'd split their HR/PA vs R and L separately and give them a multiplier to their base power number.

Lets say your prospect has a CV of 60 game power. That means he's a 73 power overall.

In the minors, that player averaged 1 HR per 20 PAs overall, but averaged 1 per 15 vs R and 1 per 25 vs L. To calculate that you'd divide 20 by 15 for R and 20 by 25 for L. That would give you a modifier of 1.33 vs R and 0.80 vs L. You'd simply multiply your base power number of 73 by the modifier to get your handedness power. For this theorhetical player, you'd have a Power vs R of 97 and a Power vs L 58.

***Now, to avoid ridiculously lopsided splits because of small samples, I've always blended my modifier with an overall league average modifier which keeps everything sane but I won't include that here.***

I do this for every tool that's on the scouting scale and I'm incorporating Fangraphs' new bat control and pitch selection grades in discipline and vision this year.

Anyway, it's a lot of work, so I'm not sure I'll ever finish it this year, but it makes the game so much more enjoyable for me, but because franchise still kind of sucks, I doubt I play it enough to warrant the 200 hours or so this takes. Hope this helps.

I use an average of MLB Pipeline and Fangraphs which is why I have them broken down in 1.25 point increments in the following table. Some FG prospects are 45+ and for those guys I use 47.5 same with the 35+, they get 37.5 as their FV.

It adds variation to the numbers. I'll also add a couple points based on ETA and eliteness of the tools compared to average but here's my baseline:

Dave,

If you could make a document and share it that would be awesome. Thanks!

I'll get something up this evening and share it.

Sorry I didn't get back to you on this. I can't get myself motivated to work on things for this game.

Here's the Google Sheet:

https://docs.google.com/spreadsheets...it?usp=sharing

So far I only have the 20-80 for hitters on there. I promise I'll put the pitching ones together tomorrow. It's a simple copy and paste but on my original sheet I have a million different formulas and pitching is a little less straight forward because I combined a couple of different things and I want to be able to explain it in a post

[AGordon1109]

Cannot wait for you to post the pitching portion! Will make life so much easier when it comes to doing ratings! Thanks for your hard work.
