Methodology

How Predictions
Work

Every prediction on Jackal XV is anchored by a structured scorecard system. Seven dimensions, scored independently, combined into a net score that maps to a win probability and predicted margin. The scorecard doesn't replace analysis — it disciplines it.

The System
01

Score

Each match is evaluated across 7 dimensions from the home team’s perspective. Each dimension is scored on a scale of −5 to +5.

02

Sum

The seven scores are summed into a net score (range: −35 to +35). Negative means the away side is favoured. Positive means the home side.

03

Predict

The net score maps to a win probability and predicted margin. The analyst then writes the verdict — the scorecard anchors the call, not the other way around.

The Seven Dimensions
HA

Home Advantage

Venue, crowd, altitude, and travel distance for the away side. A South African highveld fixture at 1,750m earns +4 or +5. A neutral or local derby sits at +1 or 0.

+5 Lions at altitude+2 typical home0 local derby
FM

Form

Last 5 results, momentum, and trajectory. A team on five straight wins versus one on five straight losses scores +5. Identical records score 0.

+4 W5 vs W10 both W3 L2-3 losing streak
H2H

H2H Record

Head-to-head history, weighted towards recent meetings at this specific venue. A dominant 8-0 record at the ground earns +4/+5. An even split scores 0.

+5 never lost here0 even split-2 poor venue record
SQ

Squad Strength

Depth, international players available, key absences, and bench quality. Accounts for Six Nations or international windows and injury lists.

+3 full strength vs depleted0 similar depth-2 key players missing
SP

Set Piece

Scrum and lineout quality. A Springbok-laden front row versus a regional pack scores +3/+4. Evenly matched packs score 0.

+4 dominant scrum0 evenly matched-1 lineout concerns
BL

Backline Quality

Halfback control, centre partnerships, and back-three finishing. Compares creativity, defensive solidity, and individual match-winners across the backline.

+3 international backline0 close-2 inexperienced 10
SG

Standings Gap

Table position differential and what's at stake. Top versus bottom scores +3/+4. Adjacent teams with similar motivation score 0. A dead rubber for one side adjusts further.

+4 1st vs 16th0 adjacent positions+2 must-win scenario
Net Score to Probability

The net score maps to a predicted margin (roughly net × 1.5 points) and a win probability band. These are starting points — the analyst can adjust if the qualitative analysis suggests the numbers are too generous or too conservative.

Why a Scorecard?

Consistency

Every report evaluates the same seven factors. A 70% prediction for one match means the same thing as 70% for another — calibrated against the same framework, not subject to whatever the analyst happens to fixate on that day.

Transparency

The scorecard shows why a prediction landed where it did. You can see exactly which dimensions drove the call and which ones were close. No black boxes.

Anchor, Not Straitjacket

The scorecard sets the starting point. If the numbers say 72% but the analyst sees an interpro derby wildcard or a weather-affected fixture, the verdict explains the override. The data informs; it doesn't dictate.

Defensible

It's harder to accidentally call something 90% when the form dimension is −2 and the set piece is even. The structure forces honest assessment across every area of the match — not just the headline narrative.

The scorecard system was introduced in March 2026. Predictions before that date used qualitative analysis only. All predictions are for entertainment purposes — rugby is gloriously unpredictable.
