+5. **Their sheets read about twice as effective as they are, and the number doing it is
+   Dodge 68.** This one is arithmetic off two published numbers, not a measurement. The
+   column dodges at **68%** (`The Quiet Neighbours`, `tools/content.mjs`; the bestiary
+   prints it), and a defence is spent **per incoming blow** — so a skill roll is only the
+   first half of the test. A 40% attack against a fresh dodge connects about **one time in
+   eight** (0.40 x 0.32), against a sheet that reads 40%. The three who can fight in the cut
+   carry Firearm and Melee between 35 and 40. **Nobody at the table will guess that from
+   their own sheet**, and the same gap is Ashcroft's defect one level less severe: the
+   number on the page is not the chance of doing anything.
+   - **The way out is to spend their dodges, not to out-shoot them.** Each defence after the
+     first in the same round is at **-30** (`DEFENCE_STEP`, `rules.mjs`), so a defender who
+     has already dodged once meets the next blow at 38%, then 8%, then the 1% floor. The
+     second agent to connect in a round is worth more than the first — that is what
+     `check-focus` measures across the bestiary, and it holds here.

+     Bhattacharya 17.8, Renshaw 17.3, Braithwaite 16.2 — which is *above* the one-in-eight
+     the arithmetic gives for a fresh dodge, precisely because most blows in a fight are not
+     the first of their round. `tools/attackers-baseline.json`, held by `check-attackers`.
+   - **This is the other half of why the cut is a different game.** Three attackers cannot
+     spend three defenders' dodges; six can. Point 4 says the cut is short an attacker.
+     Dodge 68 says what that costs — the missing attacker is the one who would have made
+     everybody else's shots land.
+   - **Do not fix it by lowering the dodge.** Their 68% is why Act Two's answer is medicine
