A live reading from our own demand series - the shape of the signal this method works on. 570 industries are tracked daily; this is one of them.
Our own data: 391 cities and 213,208 city x industry records, all scored in-house (2026-10-08). Data base: InfoGap own records - 391 Chinese cities x 8 dimensions, 213,208 city-industry rows, 40,499 POIs (central / lifechain, 2026-10-08).

1In one line: what it does
Score a thing, it tells you what makes it valuable, and it ends with one verdict: "worth doing" or not.
2When to use it
It helps in these three situations:
You want to open a Chinese medicine clinic in Shanghai, and you have seen a table saying this combination scores well — but "high score" and "worth doing" are two different things.
What people usually do: see that someone else's shop is doing well, and copy it.
Use it: score three things separately — how easy the shop itself is to use, how good it feels to use, and whether it builds up into an asset — and it gives you one overall verdict.
You want to build a small AI dress-up tool (upload a photo, get folk costume), but you are not sure whether people play with it once and drop it, or it can sell for a long time.
What people usually do: launch it straight away and see whether anyone turns up.
Use it: score it first to see whether it is "function-led" or "emotion-led" — the two playbooks are completely different.
You have to pick one project out of several to do, and they all look lively.
What people usually do: pick the one they like most.
Use it: score every one of them and line the totals up before deciding.
3What goes in · what comes out
Inputs (this is the exact set used for the real run)
· Product name: Shanghai Chinese medicine clinic
· One-line description: in-store service; from row 15 of the gap table, city demand 0.961, direction up
· Usability, three items (efficiency, cost saving, coverage): 6 / 5 / 5 (out of 10)
· Chance of being displaced by something else: 0.4 (higher = easier to replace)
· How it feels to use, three items (reassurance, pleasure, showing off): 8 / 4 / 3 (out of 10)
· Whether it holds its value (can it be resold, do people recognise it, is it scarce): 2 / 7 / 6
What comes out
These numbers came out of it on the spot, with not one character changed:
Usability value: 0.94 (very high) — held up by "usability"
Feeling value: 0.88 (very strong) — the strongest single item is "reassurance" (against fear)
Holding value: 0.80 (good) — many people recognise it, but hard to resell
All three together: 0.877
Which type it is: 🟢 Function-led (its value comes mainly from usability)
The one-line verdict: ✅ Worth doing (build the chain), reason "overall value 0.877 is not below 0.5"
—— push the scores down (all three usability items set to 1, easy-to-replace set to 0.9) ——
Usability value drops to 0.865, feeling value drops to 0.73
Which shows the score really does follow the numbers you enter.
How to read it: Look at which of the three is highest — that one is its lifeline, and that is where you should push afterwards. In the clinic set it is "usability", so its playbook is "cut cost, raise efficiency, widen coverage"; if "feeling" were highest, the playbook would have to switch to "manufacture experience and talking points". Only move on when the total score is above 0.5.
📈One chart: three kinds of value, which one is not accumulating
Easy to use, good to feel, able to accumulate — the shortest one decides whether the thing can carry a chain.
4How to use it
There is no public calculator for this yet — the method above is the whole procedure, and on this site the inputs have to be keyed in by hand.
Write down the three groups of scores: usability (efficiency, cost saving, coverage), the chance of being displaced, feeling (reassurance, pleasure, showing off), and holding value (resale, recognition, scarcity)
Add the product name and the one-line description beside them
Work out the three sub-scores and the total the same way this page does it in section 3
Read which of the three is highest, the total score, and that one-line verdict
5Who it is for
People about to open a shop or launch a new product; people who have to pick one project out of several; people who have been told "this one makes money" and want to check it themselves before believing it.
6Common questions
Q: Are the three groups of scores something I fill in myself?
A: Yes. The ledger does not hold these scores, so the default given is a middle value that you change on the spot according to what you know. It will not go and look anything up for you.
Q: Is 0.877 high?
A: By its rules, 0.5 is the line for "you can carry on". 0.877 counts as fairly solid. But note: switch to a different category of inputs and the score barely moves — its power to tell categories apart is limited, so do not treat it as a precise scale.
Q: What does "build the chain" mean?
A: It means you can build a complete business chain around it (finding customers, closing the sale, repeat customers, repurchase — the whole set). The other way round: when the score is not enough it says "do not build yet".
✓Why this scenario exists (where the content comes from)
This scenario comes from the records of the "algorithm meets demand" round: the Shanghai · Chinese medicine clinic need was run against three algorithms, and this one was judged "useful" because "the score changes as soon as the inputs change slightly — it is not just decoration".
The inputs and outputs above were obtained by re-running the original inputs in the record: product name "Shanghai Chinese medicine clinic", description from row 15 of the gap table, total score 0.877, verdict "worth doing".
