The season chart needs a little more history — it appears once there are about eighteen months of results to draw.

Harper has raced 3 meets across 2 seasons, typically about every 7 months.

Season Gains

How each season went

How much came off inside each season, by stroke — with the monthly pace beneath it.

Measured within each season, not over a rolling 12 months — a stroke can lead one and trail the other.

2025/26
Stroke2025/26
Freestyle6.4%1.1%/mo pace
Backstroke5.5%0.9%/mo pace
Ind. Medley7.2%1.2%/mo pace

For every event raced at least twice in the season, the best of its earlier races against the best of its later ones, per month between them — then averaged by stroke. Each pool is measured against itself. The headline is that season's whole drop; the pace beneath it is per MONTH and is not an annual figure — time comes off in bursts, so multiplying by twelve overstates a year badly. A season whose races fell close together can show a fast pace on a small total. This is also the short view of one season; the multi-season trend on the pathway page answers a different question and will not match.

Racecraft

Front-ender

Across 10 raced splits, Harper’s back half runs +6.6% vs the front (dive-adjusted) — spends early and pays late — back-end endurance is the cheapest time on offer. ≈1.7s a race is sitting in the back half — available from pacing alone.

“To next milestone” is how much time must come off the PB to clear the next tier. “12-mo gain” compares the last year’s best with the best before it.
