Thirty-one screens. Twenty-seven of them everybody sees, in the same order. The four in mulberry are conditional — each is skipped when the question above it gets its opt-out answer. That is the whole of the branching: four independent yes/no decisions, sixteen possible routes.
Each rule looks only at the screen directly above it, and they never interact — so the routes are just every combination of four independent choices.
| Screen | Decided by | Skipped when the answer is | Why it is conditional |
|---|---|---|---|
| 1.6 | 1.5What’s changed in the last few years? | Honestly, not much | It’s physiology, not willpower — the screen explains the mechanism behind her symptoms. Nothing to explain if she reports none. |
| 2.7 | 2.6Where do you feel stiff or achy? | Nowhere much | These aren’t separate problems — ties her aches together into one cause. Needs at least one ache to tie. |
| 2.9 | 2.8Do you ever leak? | Never | Then we won’t ask you to jump — explains why impact work is being left out. Only relevant if it is being left out. |
| 4.2 | 4.1What got in the way before? | Nothing’s really stopped me | Fifteen minutes is not selfish — answers the barrier she named. Nothing to answer if she named none. |
On the multi-select screens the trigger is “only”. Ticking the opt-out alongside a real answer still shows the interstitial — a stray tick cannot hide a screen she should see.
Both routes end at 5.1 and continue identically through 5.2, 5.3 and the paywall. The spread between the two is four screens — about 13% of the funnel.
