Score Trend
Enter your rounds with a date and score. This tool orders them chronologically and, if you choose a window, adds a rolling mean, without predicting a future score.
| Date (optional) | Score | |
|---|---|---|
Enter at least one round.
A description, not a forecast
This tool shows what your entered scores have done, ordered by date. It does not project where your scoring is headed next, fit a statistical model, or claim any predictive power. A trend line drawn through past data describes the past; treating it as a guarantee about your next round is a common and understandable mistake this tool deliberately avoids encouraging.
Why a rolling mean is optional
A rolling mean smooths out the natural round-to-round noise in golf scoring, but it also delays showing a genuine recent change until enough rounds fill the window. Leaving the window blank shows your raw series; choosing a window of, say, five rounds trades some responsiveness for a steadier read. Neither choice is more correct, and this tool lets you pick per view rather than baking in one default.
What happens with a missing date
A round without a date cannot be placed in true chronological order, so this tool lists it after every dated round rather than guessing a position for it. If you have several undated rounds, consider adding at least an approximate date so the ordering reflects reality more closely.
Reading a short series honestly
Three or four rounds is not enough to distinguish a real change in your golf from ordinary variance; even a rolling mean over that few rounds will swing with a single unusually good or bad round. Treat any read from a short series as a starting point for more data collection, not a conclusion.
Where this connects
A score trend pairs naturally with the Round Comparison tool for a closer look at any two specific rounds in the series, and with Par-Type Analysis for a different way of slicing the same underlying rounds.
Frequently asked questions
Does this tool predict my next round's score?
No. It only shows what your entered scores have already done, ordered by date — it does not project where your scoring is headed or fit a statistical model. A trend line through past data describes the past, not a guarantee about your next round.
Should I always use a rolling mean window?
Not necessarily. A rolling mean smooths round-to-round noise but delays showing a genuine recent change until enough rounds fill the window. Leaving it blank shows your raw series; neither choice is more correct, so this tool lets you pick per view.
How many rounds do I need before a trend means something?
Three or four rounds is not enough to distinguish a real change from ordinary variance — even a rolling mean over that few rounds will swing with a single unusually good or bad round. Treat a short series as a starting point, not a conclusion.
