Coming in late, but anyway
((0.689* BB units )+(0.722* HBP units)+(0.892*1B units)+(1.283*2B units)+(1.635*3B units)+(2.135*HR units))/(AB+BB units+HBP units)
I've never seen Steve F formula, but I do know that any kind of formulas that predict run values can always be transformed to skip the 2b units/ 3b units without much errors. So you don't need to know the 2b/3b units. For example
(0.892*1B units)+(1.283*2B units)+(1.635*3B units)+(2.135*HR units) is roughly equal to
0.5*Hits +0.392*TB+0.067*HR
Only triples will be slightly off if you compare the two formulas, but they are so rare that you can skip off that difference---or if one wants to be picky, a slight adjustment could be done for the few players that have a lot.
Also, Steve said that superadvance takes off walks away from supercards such as Maddux, and that explained why walks are valued less. On this, two points
1-But in the good old days of Bernie H, he confirmed that this specific rule was OFF in online strat. So walks should be valued just as hbp.
2-But moreover, I don't think this is the reason why walks are valued less than than HBP. In most sabermetric formulas, which is based on real life, walks are valued less than HBP because walks tend to be more frequent in situations where sending one extra player on base cost less. Compared to HBP, Walks are much more prevalent with first base empty than with first base occupied---you know the typical semi-intentional walk.
If you look at any run expectancy matrix, consider for example this one based on 2014 values:
http://www.baseballprospectus.com/sorta ... id=1657937you see that, with no one on base, no out, a walk has, on average, led to 0.36 runs. But with two outs, man on second, the walk has, on average, led to 0.11 runs, much less. In real life, whey you multiply these values with the frequencies with which walks happen, you get a value lower than 0.36 runs, in the range of 0.32-0.34 runs. But in Strat, walks happen independently of the situation (again, this is true because some of the superadvanced options available on the computer game are off in the online strat game---I'm thinking of the "pitching safely" mode or somethink akin to it). And it should be upgraded from standard sabermetric formulas based on real life---in steve's case, I would simply equal walks to hbp at 0.722.
Just to repeat: I'm not pushing for steve's formula, never seen it, so I can't judge whether the formula is right. But steve is a heck of a player, so I'm pretty sure he has some solid data to rely upon.
