Sixteen crews went afloat for the Round of 16 on Wednesday, and the story of the day was the boat that didn't come back. Kings College beat Deerfield by two and a quarter lengths, and with that the last American crew is out of the Princess Elizabeth. Phillips Exeter went on Tuesday; Deerfield went on Wednesday. The half of the Day 1 recap that belonged to the United States is now closed.
At the top of the draw there was no such drama. Radley put four and a half lengths on Abingdon and posted the fastest winning time of the day, 6:22. St. Paul's went 6:23. The two crews the model likes most are the two fastest crews on the water, they are pulling away from the field, and — a detail worth holding onto — they sit in the same half of the draw, so they cannot meet before the semi-finals.
The honest note is the one about the model, and it is the same note two days running. On Tuesday the rating's one clear miss was an American, Phillips Exeter. On Wednesday its one clear miss was the American it was most sure about. Deerfield carried the tightest credible interval of any contender into Round 2; the model rated the Americans a shade high all spring, and Henley has now corrected it twice.
| Pos | Team | Time | RPI Δ |
|---|---|---|---|
| 1 | Kings College | 6:31.00 | - |
| 2 | Deerfield | — | - |
RPI is on the four-digit scale anchored around 1500. The 90% credible interval after each rating is the model's honest statement of how much it does and doesn't know. The whole field rowed faster on Wednesday than Tuesday — 6:22 to 6:42 for the winners, against 6:37 to 7:05 a day earlier — so read the times as a faster stream, not sixteen crews suddenly finding a length.

The last American is gone
By reputation, Deerfield were the American crew most likely to make the Berkshire bank nervous — the fastest winner of Day 1, and the boat the model was most confident about. By Wednesday afternoon they were on the trailer. Kings College led early, held the middle, and had the verdict at two and a quarter lengths before the enclosures.
The rating's reaction is the clearest single move of the regatta so far. Kings College went in at RPI 2045, a length-and-a-bit underdog on the model's numbers; beating a fancied crew by open water lifted them to 2125 (2093–2158), a jump of eighty points, and their interval is the tightest of any crew still standing — the model now knows exactly how fast they are. Deerfield dropped to RPI 2071, down forty-one, still a strong number and no reflection on a good crew. It just isn't a Henley number any more.
Set it beside Tuesday and a pattern forms. The two crews the model expected to advance and didn't were both American: Exeter by a length and a half on Day 1, Deerfield by open water on Day 2. Every US eight that entered the Princess Elizabeth has now been beaten by a British or Australian crew, and the model's spring habit of pricing the Americans a touch high has been marked to Henley's market on consecutive days.
The favourites answered
At the front, the questions got shorter answers. Radley beat Abingdon by four and a half lengths in 6:22 — the fastest trip of the day and the kind of margin a model doesn't fit inside a probability interval. They climbed to RPI 2214 (2177–2255), and the field's clear number one. St. Paul's answered in 6:23, two and three-quarter lengths clear of the Australian club KAND, and sit second at 2204 (2158–2252).
The draw has already set the collision. Radley and St. Paul's are in the same half of the bracket, which means the two best eights in the Princess Elizabeth cannot meet in the Final — if they meet at all, it is Saturday's semi. Everything the rest of the week is rowing toward is on that side of the sheet.
Behind them, Shiplake (RPI 2143) and Hampton (2118) did what the model asked, Hampton by only half a length over a Windsor Boys' crew whose rating the model still can't pin down. Bedford took the other third-of-a-length verdict of the day, edging Reading in 6:26.
The crew the model can't rate fast enough
The runaway mover of the regatta is Sydney University. The model held no rating for them on Monday night. Two wins later — the second a third-of-a-length squeeze past Shrewsbury in 6:27 — they sit at RPI 2081, up more than two hundred points in forty-eight hours. The interval is still the widest of any survivor (2008–2164): the model has seen enough to know they belong and not enough to say exactly where. That uncertainty is the story. A crew the rating met on Tuesday is into the quarter-finals of Henley's blue-riband schoolboy event, and the numbers are sprinting to keep up.
The field, by the model

What the quarter-finals hold
Eight left, four races, and the draw has been kind to the favourites and cruel to the tightest tie. When the Princess Elizabeth returns to the water later in the week:
- Radley v Bedford — the top rating in the draw against a Bedford crew that squeezed into the last eight by a third of a length.
- St. Paul's v Sydney University — the second seed meets the regatta's fastest-rising unknown; on the model's numbers a clear St. Paul's win, but with the widest interval on the board attached to the other lane.
- Kings College v Hampton — the closest quarter-final on the model, seven points of RPI between them, and the crew that put out the last American against a crew that has answered every question so far.
- Shiplake v St. Edward's — the Day 1 giant-killer, still standing, against a crew a hundred RPI points clear of it.
What the model learned, in three sentences
Day 2 belonged to the seeds again at the very top — Radley and St. Paul's rowed the two fastest times and pulled clear — but it took its one real bite out of the Americans, sending Deerfield home behind Kings College and leaving the Princess Elizabeth without a US crew for the first time this week. The rating's largest move was Kings College, up eighty points into the tightest interval of any survivor; its most honest shrug remains Sydney University, up more than two hundred points and still bracketed by the widest interval on the board. The line to watch runs to Saturday, where — if both take care of business first — the two crews the model can't separate at the top, Radley and St. Paul's, are set to meet a round before the Final.
