The verification standard

Every claim on this site names its source, and any number that comes from a model instead of a measurement carries a label on the chart.

01

Sources named

Broadie's 2011 ShotLink data, Stagner and Arccos amateur numbers, USGA and R&A rough studies, GOLFTEC fitting data. Every claim traces to a name you can look up.

02

Modeled numbers labeled

When a figure is extrapolated rather than pulled straight from a source, the chart says so, right next to the number.

Who runs it

I'm Sunny Rathor, and I run Dogleg Data. Most amateur golf advice descends from tour numbers, so I test what holds up for the mid-to-high handicap golfer and name the source behind every claim.

By day I'm a Staff Data Analyst, ten years into building the same kind of work this site runs on: A/B tests, causal inference studies, and the semantic data models that turn raw numbers into a straight answer, at companies including Trust & Will, Charles Schwab, TD Ameritrade, and CVS Health. The same standard carries over here: every claim names its source.

Fairway vs. Rough is analysis Nº 001. Distance gapping, putting reads, and club selection under pressure are all on the list. If a piece of conventional wisdom hasn't met real data yet, I'll run the numbers on it.
