About GolfVectorLab
Recreational golf produces the same handful of decisions over and over: what handicap should I play off today, does my bag actually cover the distances I need, how far should I plan to hit a club in the conditions I am facing, and how do I set up a fair game for a group. Search results usually answer each of these with a different kind of site: an official rules calculator, a generic number-cruncher, a scoring app that wants an account, or a shot-tracking product built around a subscription. None of them are built to carry one answer into the next question.
GolfVectorLab starts from the opposite direction. It is one connected system of interactive tools that share the same private, browser-local information about you and your bag, so a distance you enter once for a gapping review can also support a practice plan or a round brief without re-entering it. The goal is not to add another calculator to the pile. It is to make the relationship behind a golf number visible, so the number is easier to trust and easier to act on.
Who builds this
GolfVectorLab is built and maintained by an independent developer, not a golf equipment company, a handicap authority, or a data broker. There is no product to sell inside the tools themselves. The site pays for itself the same way most useful reference sites do: it stays fast, free, and static, with no account required to use anything on it.
How it is built
Every calculation method used on GolfVectorLab is sourced, documented, and tested before it appears on the live site. Rule-based results are checked against published USGA and The R&A material for the World Handicap System. Estimates that rely on a player's own input are always labeled as estimates, with the assumptions and uncertainty stated next to the answer rather than left out. See the methodology page for the detail behind that process and the sources and assumptions page for the references themselves.
