How to read this map

One rink, both ends while Mark Jankowski is on the ice: what the team generates on the left, what it concedes on the right. Every attempt is a Gaussian bump of height = its model xG, summed per 60 minutes of ice time (a player's exposure is time, not games). The controls switch the surface (xG heatmapvs league, the league baseline per team-hour at the same strength) and the markers: × goal · on net · missed · small blocked — and own shots narrows the left end's markers to attempts Mark Jankowski took.

The page opens at 5v5; empty-net attempts are excluded throughout. On-ice membership comes from the shift charts; attempts without usable shift coverage are absent from both ends. Blocked-shot membership cannot be cross-checked against the play-by-play, so treat blocked-marker detail as softer than the rest.

Percentiles rank against the other forwards over the display floor at the selected strength — a non-strength filter (rush, period, …) moves the bars but keeps that strength's spread as the backdrop.

Ranked against forwards; the band behind each bar is that cohort's spread (p5–p95, middle half brighter, dashed median), so where a bar lands against its band is the rank — the ordinal beside it makes that exact. The per-shot rating is quality only: it says nothing about how many attempts a player generates or faces, which is what the attempts sub-row is for.

Usage & context

descriptive · not modeled
The job the coach handed Mark Jankowski, not how well it went. Not a modeled component: each is its own metric (minutes, a rate, a TOI share, or opponents'/teammates' net xG-RAPM), shown with a cohort percentile only where one exists, never added together. Not a grade. The deployment rows are measured over the same 5v5 stints the isolate is fit on (regular season + playoffs); ice time and the penalty rates are all situations, every game — penalties create non-5v5 time, so a 5v5 denominator would inflate every rate.

A skater absent from the fit counts as exactly cohort average (0) in QoC/QoT — the same claim ridge shrinkage makes. Penalty rates are descriptive only: taken-rate includes defensively correct penalties, and neither side is opponent- or deployment-adjusted. Nothing here is priced in goals.

Observed values reflect the active rink filters; modeled values are fixed at their full-season fit.

On-ice numbers pair the regular-season shot set with shift-chart membership; skaters and goalies under the display floors are fit but not shown. Modeled rows come from the value artifact keyed to RAPM fit rapm__c5b9b663 on flat__joint_structure_xg__4f64c88b (the joint-xg structural baseline), with ratings from joint__baseline_xg__42ccb89b (as of 2026-06-14) — separate surfaces from the box-score xG model badged in the footer.
