The UBKT Perceptual Advantage Rubric
PA is a composite metric that quantifies a pitcher's sport-specific intelligence and field control. It measures the cognitive and strategic skills that allow a pitcher to maximize the effectiveness of their raw physical output (as measured by BSS).
Scoring Methodology
PA is derived from the average of five core components. Each component is scored on a 5-point scale from 0.0 to 1.0 in increments of 0.25.
PA = (GP + HR + DT + CL + TC) / 5Score Anchors
How PA Affects SSQ
SSQ = BSS × (1 + 0.25 × PA)With k = 0.25, a perfect PA score (1.0) adds up to +25% to BSS. PA only amplifies — it never penalizes. A pitcher with PA = 0 has SSQ = BSS.
Component Definitions & Anchors
Clear, documented pre-game plan; actively exploits hitter tendencies; sequences are designed to set up specific kill pitches; purposefully varies patterns to avoid predictability.
Has a standard plan and a go-to sequence; makes some adjustments based on scouting reports; can occasionally become predictable.
Relies on a general philosophy (e.g., "fastball in, breaking ball away") rather than specific, tailored sequences; often follows the catcher's lead without deep intent.
Primarily throws favorite pitches in favorite zones with little regard for sequencing; patterns are easily identified.
No evidence of a game plan; pitch selection appears random or reactive.
Application Notes
For Historical Pitchers
Scores are assigned based on a synthesis of:
- •Scouting reports and contemporary analysis
- •Game footage analysis
- •Statistical indicators (walk rates in high-leverage situations, performance variance with runners on base, times-through-order splits)
- •Catcher and coach testimonials (where available)
For Live Pitchers
The rubric is completed by a trained coach or analyst during or immediately after a game or bullpen session. It can also be used as a self-assessment tool.
Minimum Evidence Checklist
For each component score to be defensible, the evaluator should have access to at least two of the following:
- •Game video (minimum 3 innings or 50 pitches)
- •Scouting report or contemporary analysis
- •Relevant statistical splits (leverage, count, times-through-order)
- •Direct observation notes from a coach or catcher
