One good curve proves nothing.
Analysis pulls a backtest apart — 10 views, from monthly returns to start-date sensitivity — to show whether the result survives scrutiny, or just got lucky.
10 views, one verdict. Every tab the app shows, on the same run — click through each angle.
The bad months stay visible. 2022 reads red, cell by cell — a strategy you'd actually have lived through, not a smoothed curve.
Luck gets its own trial. Start-Date Sensitivity re-asks the question from every starting month — it has its own section below.
The interrogation
Ask the result three hard questions.
Any curve can look good from the right angle. These are the views that catch a result lying — or prove it doesn't.

The luck test
Would a different month have changed everything?
Start-Date Sensitivity re-runs the question from every possible starting month — across 1, 3, 5, 7 and 10-year windows — and shows the whole spread: best, worst, and typical.
CAGR by start month
The spread is the verdict. A tight range across start months reads as method; a wide one reads as luck. Here it's 10.1 points — you decide if that's tight enough.
The floor matters most. Worst CAGR is the month you'd least want to have started — if you couldn't have lived with it, the average doesn't matter.
No competitor shows you this. One backtest is one draw from the deck. This view is the whole deck, face up.
