PECOTA 2022: New Functionality for The Ax


The AX offers new adjustability on two major settings so that you can customize valuations to reflect your own specific outlook for the coming season. By default, The AX (see original intro article here) generates values using each player’s 50th percentile PECOTA projection, and playing time estimates from BP’s Depth Charts. Both of these can be adjusted within the AX interface, allowing you to select custom performance or playing time estimates for as many players as you like, and the AX will automatically adjust the universe of values to reflect these adjustments. The performance selector allows you to apply any of 13 projection levels generated by PECOTA, while the playing time selector applies a linear adjustment to re-calculate counting stats for the specified amount of playing time (PA for hitters or IP for pitchers).

The editable categories are “%” for the percentile projection, “PA” for batter playing time and “IP” for pitcher playing time. By clicking into the blue, linked number you will be presented with the ability to select a given projection, or a slider for PA/IP respectively:

We’re targeting future enhancements to help you assess and manage the cumulative impact of many playing time adjustments, but for now it’s important to remember to keep the total budgeted playing time relatively consistent across all players. We hope you enjoy the new functionality provided by the adjustable playing time sliders in The Ax, as we work to develop additional features.
