For the sake of transparency, there was a bug on the team totals page for pitchers values only where some pitchers who switched teams mid-season were not being included in the team totals.
This did not effect any of the individual pitcher values, only the team totals.
Update: There’s been one additional change made where relievers are now not as highly influenced by leveraged. This change was made to properly align positional player win values with pitcher win values. Only pitchers who pitched in extremely low leverage, or extremely high leverage situations will be effected, and at most by about 1 win.
