The same Kintetsu 2025 dataset run through logistic regression and a random forest. The model surfaced something the pairwise analysis missed, and was honestly worse than the naive baseline on accuracy. Both findings matter.

Across 14 matches with the Kintetsu Liners in 2025, the things I had been told to coach harder weren’t the things that decided games. Discipline, turnover security, and conversion efficiency. Possession is not on the list.

Sixty years of research on rugby player anthropometry, one season of Japan League One data, and the question of whether height still matters at the elite level once everyone is big enough.

Velocity-based training, daily maximums, and a way to manage week-to-week loading without testing 1RMs that wreck your athletes.

Why progressive overload through volume, not intensity, is the under-rated lever for hypertrophy and durability.

How the Kintetsu Liners use GPS technology for daily, weekly, monthly and yearly load monitoring and performance tracking.

A modified APRE block design that has produced 7 to 11 kg gains in first and second year players over nine months.

Why "fill in the gaps" individualised programming beat one-size-fits-all in our preseason. 49 of 50 players ran faster.

A season of weekly drop-jump testing against subjective wellness scores across 50 athletes, set against the published athlete-monitoring literature. The finding I expected and the one I got were not the same.
