1) 2%-Games played- I'm not certain this can't be taken into account with plate appearances in the formula below. I wold eliminate it completely to avoid duplicity.
2) 3% playoffs- In a mathematical formula, this really doesn't belong. Does a walk-off home run hold more statistical importance than a home run in the 2nd inning? Statistics and mathematics would say no. Perhaps you could drive a formula multiplier to derive how to statistically define clutch.
3) 5% position played(catchers do get a little extra here).- Again, this would be better addressed when assessing defensive value. The notion that catchers add more value because of their control of the pitching side of things is interesting (and probably correct). I'm just not sure how to quantify it.
4) 2% rank at position played- Redundant.
5) 44%- formula using (RBI+Runs-HR)/PA and (RBI+Runs-HR)/total team runs scored)- This has many troublesome issues. I like where you are going with the formula but I really don't understand where team runs is relevant.
5) 44% using a version of RC27 that includes baserunning and other advanced statistics... also using a different version of total bases(not 1 point for single, 2 point for double and so on). The formula I have for RC27 is "(Runs Created)/(At bats-hits+caught stealing+sacrifice hits+sacrifice flies+GIDP)*27". Can you detail a little more about how you have altered that?
Overall, I think the model is flawed for the simple reason that it lacks assumptions. For instance, can you tell me how much you are attempting to weight offense v defense? What percentage does baserunning figure when determining overall value. I'm not trying to dictate the direction of your model, only assess if it achieves what you set out to. It is obvious you put a high value on the offensive side of the ball. Can you justify why more value is added offensively vs defensively?
I don't really have much to add regarding pressure situations. I know there have been attempts to quantify it using weighted averages based on situational things but I have never seen on I liked. I do believe there is validity to pressure situations within a game but I am not as certain that applies to the general pressure of being in a pennant race.
I will read through the follow-up comments and may have more to add. I think it was a thoughtful attempt at measuring how you feel and I thank you for sharing it.
