If you got the ratings guide, there is a Readme document in the download folder for the ratings, which explains some of this.
For example, on the hitter section:
Bb = Walk chances
HIT = Hit chances
OB = On-base chances (walks+hits+HBP)
TB = Total Bases (from hits only)
Now, it is important to note that this is CHANCES. It isn't an "out of 100 AB" type of thing. It is "out of 108 random dice rolls." Where do I get 108? Each plate appearance consists of 3 6-sided dice rolled to determine the outcome. A single die determines the column 1-2-3-4-5-6, where 1-2-3 are the hitter card and 4-5-6 are the pitcher card. The other 2 die are added together to get a result from 2 to 12, where 7 is most frequent (occurring 6 times) and 2 and 12 are least frequent (only once each). The total number of CHANCES per CARD is 108. This reflects all 36 of the possible outcomes per column and 3 columns per card. (36 x 3 = 108)
So, a player with 18 BB chances and 24 hit chances and 2 HBP chances would have total OB chances of 44. 44/108 is 40.74%, which seems really good; however, you are also rolling on the pitcher card 50% of the time, so that player would have a chance of reaching base 20.37% of the time FROM HIS OWN CARD. Obviously, you could reach base off the pitcher's card too.
Total Bases would roughly help you calculate SLG. It is the total bases FROM HITS ONLY. So a player with 24 hit chances and 30 total bases is mostly hitting singles. A player with 24 hit chances and 48 total bases is averaging 2 bases per hit. Now, that could be 12 singles and 12 triples (unlikely), or it could be 12 singles, 6 doubles, and 6 HR's (more likely).
The ratings system tells us how many HR chances there are and how many BallPark HR chances there are. Normal is not 10 for BP chances. Normal is an 8. So if you are in a ballpark that is an 8-8-8-8, then you can roughly expect "normal" HR results. Higher than that will increase HR's and lower than that will deflate HR's.
Sorry if that wasn't on point ... But that's the ratings guide breakdown as I understand it.
