Its called Weighted Factoring. Not to be taken seriously outside of one weighted factor per statistic. OPS+ is already over the line. Two weighted factors, park and league. Now you want to claim that the rocket ship is in there. Claim it if you want to but you are already past statistical merit in factoring for park and league as that is two weighted factors. All you end up with is a stew.
Have a venture capitalist visit your company with intentions to buy it and show him statistics with multiple weighted factors in them and he will be out the door faster than you can hail him a cab. It is in fact virtually the entire reason why even with all of the data crunching available today, a company "book" or annual report still includes a maddening number of separate line items because its money we are talking about and its the only way to present statistical data of merit.
You want to have fun with numbers....be my guest. But if the team I root for is making player personnel decisions and trade decisions based on statistics that employ multiple weighted factors in a given statistical measure and I will ask for a new front office, one that can see the forest and the trees.
On top of that you are trying to derive a weighted factor from a statistic that is already being weighted. The only way to do it would be to have a factor specific to the baseball itself. then you can develop a stat that employs that weighted factor. Even then you are kidding yourself if you think you can add it to a statistic that is already using two weighted factors. All you will have done is blended them into a mishmash of unreliable data added to what is already unreliable data as OPS+ already employs two weighted factors. Again, if you want to have fun with numbers, be my guest.But until Manfred admits what he is doing and provides you with the year by year weighting for the baseball, you are out of luck. You don't know more about the player in question using multiple weighted factor statistics. If anything, you know less.
