Computed facts and claims: what the difference means for your booking
When you read that a beach "shelves steeply" or that a transfer "takes a while," you are reading a claim. When you read a number our team measured, re-ran, and sourced, you are reading a computed fact. This page explains the difference and why it should change how much you trust what you read before you book.

What we mean by a computed fact
A computed fact is a value our editorial team produces through a defined method, from inputs we can point to. It is not remembered, estimated, or borrowed from a brochure. If the method changes, the value changes, and both are visible.
The test is simple. A computed fact can be reproduced. Give the same inputs and the same method to a second person, and they land on the same result. That property is what lets you challenge it rather than take it on faith.
How a claim is different
A claim asserts something without showing its work. "The seabed drops off quickly" is a claim. It may be true, it may be someone's impression, and you have no way to tell which. Claims are not worthless, but they carry no mechanism for you to verify them.
The problem is that claims and facts look identical on the page. Both are declarative sentences. Without a label telling you which is which, you are guessing about how much weight to give each line.
Why the distinction matters when you book
You are spending real money on a limited number of nights. The cost of a wrong assumption is a transfer that eats an evening, or a water entry that does not work with a toddler. Those are exactly the details that get written as vague claims.
When a value is computed, you can see the assumption behind it and decide whether it applies to you. A road time depends on traffic and season; a computed figure names that dependency instead of hiding it.
What makes a fact reproducible
Three things: the inputs, the method, and the source. Change any one and you should be able to see the effect on the result. That is why our callouts carry all three fields rather than a bare number.
A figure without a method is a claim wearing a number's clothes. A precise-looking value is not automatically a reliable one, and false precision is its own kind of misinformation.
Where computed facts come from in our pages
On destination pages, the values we compute are tied to a specific place: how a shoreline enters the water, how much shade a spot holds around midday, how a transfer routes from the airport. These are our measurements, and they do not exist anywhere else in the same form.
Because they are ours, we can re-run them. If a route changes or a method improves, the number updates and the old one is not quietly preserved as if it were still current.
How to read a number and know which kind it is
Look for the method and the source. If a value tells you how it was derived and where its inputs came from, treat it as a fact you can check. If it stands alone with no trail, treat it as a claim and weigh it accordingly.
A dated value is more honest than an undated one. Anything that can go out of date, a driving rule or a climate figure, should carry the date it was accurate, so you know how stale it might be.
The limits of a computed fact
A computed fact is only as good as its inputs and its method. A road time built on average conditions will not describe the worst of peak-season traffic, and it should say so rather than pretend to. Naming the dependency is part of the fact, not a footnote to it.
Precision is not the same as certainty. When the honest answer is that a value depends on the season or the time of day, we say what it depends on in the same breath, instead of leaving "it depends" standing on its own.
What this means for how you use our advice
Trust the numbers that show their work, and treat the rest as opinion to be weighed against your own priorities. That is the whole point of separating the two: not to make claims disappear, but to let you see which lines you can independently check.
If a page hands you a figure with no method and no source, that is a signal, not a verdict. Ask what it depends on. A number that cannot answer that question was never a fact to begin with.
What works
- A computed fact can be reproduced from stated inputs and method
- Each value carries its source, so you can verify it independently
- Dependencies like season and traffic are named, not hidden
- Values that can go stale carry the date they were accurate
What does not
- A computed fact is only as reliable as its inputs and method
- Precise-looking numbers can still be wrong if the assumptions are
- Claims and facts look identical on the page without a label
Who should go somewhere else
readers who want a single verdict — this page explains a method rather than ranking places
Instead: start from a destination page that applies the method to a specific location
Questions people actually ask
what is a computed fact
A computed fact is a value produced by a defined method from inputs you can point to. It is reproducible: give the same inputs and the same method to someone else, and they reach the same result. That property is what lets you verify it rather than take it on trust.
how is a computed fact different from a claim
A claim asserts something without showing its work, so you cannot check it. A computed fact carries its inputs, its method, and its source, so you can. On the page both look like plain statements, which is why we label which is which.
why should i trust a computed number over an opinion
You do not have to trust it blindly. Because it shows its method and source, you can test whether the assumption applies to your trip. An opinion gives you no such handle. That said, a computed number is only as good as the inputs behind it.
can a computed fact be wrong
Yes. A value built on average conditions will not describe the worst case, and a precise-looking number can rest on a flawed assumption. The difference is that a computed fact names its dependencies, so you can see where it might break down for your dates.
how do i tell which numbers on a page are verifiable
Look for a stated method and source, and a date on anything that can go stale. If a value shows how it was derived and where its inputs came from, treat it as checkable. If it stands alone with no trail, treat it as a claim and weigh it accordingly.
