Is Strat-O-Matic Sabermetrically Correct?

I noticed 3bx is almost always in ONE column at # 4 on pitchers cards. 2bx is usually at #8, 1bx usually is at #12 on TWO columns per side.

We know that SOM rates a lot of things amazingly well: fielder's range and arm, HRs and doubles, etc...

What about flyball to groundball ratio for pitchers?

We can be confident K/9 is accurate, but I wonder about GB/FB.

I think Strat does approximate those seen in real life, but they don't replicate the extremes, that's for sure, because all pitching cards have 30 chances of DEF-XX (such as 2ND-gbX), and every position is fixed in the number of chances (second base have 6 chances on all cards, that is why you see so much 2nd-gbX at 8 and 12).

The gbX chances have zero to do with adjusting GB/FB ratios. SOM manages this by the non-range chances on the pitcher card. The range chances are only to incorporate the D you put behind the pitcher into the sabermetric equation.

How does it work? SOM adjust the gbAs, not gbXs, or fbAs, in the case of fly ball pitchers, or they add Ks in the case of strikeout pitchers and subtract either gbAs or fbAs, and yes, of course they modify for extremes, so when you check the CD-ROM, for instance, you see that certain pitchers have the max gb outs on their cards (11.1% I think in most cases, though a few have more).
