Why a Tipster's ROI Lies — We Analysed 20 of the 'Best'

A tipster advertises "+93% ROI". Incredible, right? We checked — across 20 of the "best" football tipsters listed on the proofing platforms. Here is what that number actually hides.

The "+93% ROI" tipster, in full

The tipster topping the football charts shows a +93.2% return on investment. But pull the rest of the numbers and the story collapses:

Strike rate: 20% — four of every five picks lose.
Average odds: 26.55 — these are long shots, not bankers.
Period: the last 3 months. Not a career. A quarter.

Twenty long shots a week at odds of 26, for twelve weeks, will swing wildly. Hit a couple extra and you are "+93%". Miss them and you are deep in the red. That is not skill — it is variance dressed up as a track record.

ROI on its own is meaningless

A return figure tells you nothing until you also know:

Sample size — 30 picks or 3,000? Small samples are noise.
Average odds — +20% on 1.90 favourites is a different planet from +20% on 8.0 shots.
The period — and crucially, who chose it. "Last 3 months" is almost always the window that looks best.

Here is the same top list, with the context the headline leaves out:

Tipster	Headline ROI	Strike rate	Avg odds	Window
LDEMO/N_X	+93%	20%	26.6	3 months
Brainiac	+31%	19%	12.5	6 months
Clean Sheet Merchant	+29%	39%	3.5	12 months
Pask	+20%	65%	1.97	6 months

The flashiest ROI comes from the lowest strike rates on the longest odds over the shortest windows. The most credible line — Pask, 65% at 1.97 — is mid-table on ROI and almost certainly more sustainable. The leaderboard rewards exactly the wrong thing.

The one number that actually measures skill

If you want to know whether someone genuinely beats the market, there is a single honest metric: closing line value (CLV) — did they take a price better than where the sharp market closed? Beat the closing line consistently and you have a real edge. Lose to it and no hot streak will save you long term.

Almost no tipster shows you their CLV. Most will not even show you the actual picks before kick-off — the selections are paywalled, so the "record" can never be independently checked.

What we do instead

We log picks before kick-off, settle them on the result, and measure CLV against the closing market — and we publish the losses too, including our own. It is all on our public, independently-timestamped record, and we audit other tipsters the same way — only counting what we can actually verify.

So next time you see "+90% ROI", ask three questions: over how many bets, at what odds, and who picked the dates? Usually, the answer is the whole story.
