At the start of the 24/25 season, I set out with a performance goal I could influence through training prescription. I wanted to score the most points in the closing twenty minutes of each game compared to every other team, and I wanted to concede the least in that same window. Unlike match GPS, which I find has weak or even negative relationships with match performance (more on that to come), I felt that actual match output, points scored and conceded, was the KPI worth chasing for fitness and conditioning.
To check where the program landed, I pulled the points data from the 2025 D2 season. Eight clubs, fourteen rounds, 56 matches in Japan Rugby League One. Per club, per 20-minute period, the average net points scored.
Kintetsu's closing-twenty number is plus 8.07 points per match: plus 11.5 scored, 3.4 conceded. The next club on that metric, Green Rockets NEC, is plus 5.14. Five of the eight clubs are net negative in the closing twenty. Toyota Shokki runs plus 7.6 in the 20-to-40 period, comparable to Kintetsu's closing-twenty number, but the same Shokki cell drops to plus 1.1 in the final twenty. Both of these teams were our strongest opposition.
What this is, and what it isn't
Net points is not a fitness metric on its own. A team can outscore the opposition late because they were better, because the opposition gave up, because the bench arrived heavy, or because the score state had already tilted. Any one match could carry any of those explanations. I still felt that a team that is consistently strong in the closing twenty, that consistently closes games, would be the hallmark of a fit, robust, and hard-trained squad.
Across fourteen matches per club, against eight different opponents, that variance averages out. What's left is a pattern about which teams stay productive in the closing twenty while most fade.
This piece is the points-only version of that case. The training side, periodisation, weekly volumes, and the kind of work that puts a squad at plus 11.5 points in the closing twenty, sits in the companion post.
The shape of the season
Two curves from the same data: Kintetsu's net by period, and the league mean across the other seven clubs. Kintetsu's curve climbs from plus 3.0 in the first twenty to plus 8.1 in the closing twenty. The league mean drifts sideways through the first three periods then drops, ending the match in negative territory.
The closing twenty, ranked
Kintetsu plus 8.1, more than 50% larger than the next-best team. Six of the eight clubs are net negative in this window. That's the league pattern. Most teams concede more points than they score in the closing twenty, and the fade is consistent enough across the season that it shows up in averages.
The 60-80 minute period is Kintetsu's highest-scoring period and its lowest-conceding period. That's the inverse of the league pattern.
Why this looks like a conditioning signal
Three observations support a conditioning read.
The gap between Kintetsu's closing-twenty number and its own first-twenty number is the only positive gap of that direction in the league. Most teams score and concede roughly evenly across the four periods, with a soft fade at the end. Kintetsu's curve climbs. Could this be that we are fitter and stronger, and outlast the competition? Hard to prove from one season of descriptive data, but the pattern is consistent with that read.
Opposition concessions in the closing twenty drop to 3.4. The defensive number falls along with the offensive number rising. Teams that fade only on attack but hold defensively are doing one half of the work; this is both halves.
The pattern is consistent across the fourteen rounds. It isn't carried by one or two outlier matches. The closing-twenty net was positive in eleven of fourteen, including against the league's other top-three sides.
Does the closing twenty matter for the league table
Plotting each D2 team's closing-twenty net against its full-season points differential gives a Pearson correlation of plus 0.88. R-squared 0.78. Across eight teams and one season, the closing-twenty number explains roughly four-fifths of the variance in how clubs finished on points differential.
The line isn't perfect. Toyota Shokki finished first on differential at plus 216, with a closing-twenty net of only plus 1.14 points. Shokki won the league by winning earlier in the match rather than late. They also had a strong start to the season and we had a poor one. The closing-twenty number is a strong signal, not the only signal.
The reverse holds too. None of the bottom-five teams on differential had a positive closing-twenty net. The league pattern is that teams which finish badly on aggregate also bleed points in the closing twenty. Closing-twenty performance is necessary for a top-three finish on differential, even if it isn't sufficient on its own.
What I'm not claiming
I'm not claiming this is causal. The post is descriptive. Teams that win the closing twenty win more matches and rack up more season points. Are they fitter? Are they stronger? Are they just better tactically, wearing the opposition down?
Being ahead also creates the score-state tactical choices that feed back into the closing-twenty number itself. Some of that loop is conditioning, some of it is the tactical posture that comes from being ahead. Untangling those is a different post.
I'm also not claiming the league-wide context will hold for 2026. Division 2 in 2025 was eight clubs over fourteen rounds with sample sizes that, while better than single-team analyses, are still small for any one period. The next-best closing-twenty number, Green Rockets NEC's plus 5.1, is close enough to Kintetsu's that a stronger 2026 from one of them could compress the gap quickly.
What I am claiming is the descriptive headline. Across the 2025 D2 season, Kintetsu won the closing twenty minutes by the largest margin in the league. That's the dataset.
Where this number fits
Two uses for this number, both about prioritisation rather than recruitment.
I use it for pre-season planning. The closing-twenty net is a single number that aggregates a lot of fitness adaptations into one outcome. If the goal of a conditioning block is to hold late-game capacity, the closing-twenty number across pre-season friendlies is the test. If it moves, the program is working; if it stays flat, the program isn't.
I also use it for in-game decisions. The league fade is real enough to plan around. Six of eight clubs concede more than they score in the closing twenty. A team that can hold or extend its scoreline in that window has a reason to think differently about bench timing and tactical posture in the 50-to-60 transition.
What the next post is about
The closing-twenty number is the outcome. The training side is the cause, or at least a candidate cause, and the part I want to show in detail.
In the companion post I cover the annual periodisation curve, weekly volumes by phase, position-group splits, and the match-pace tagging behind every full-squad session. Squad-mean training distance week by week across the season, the in-season retention of pre-season volume, and what one of the hard in-season Thursdays actually looked like drill by drill. "How we trained to stop fading."
Most teams in this league fade in the last twenty. We built the squad that didn't.
