#Year-on-Year Comparison

A year-on-year comparison sets your results from the same contest side by side across several seasons. It is one of the most reliable ways to measure progress, because the contest, the rules and your own station stay the same while the numbers change. Useful measures include QSOs per operating hour, multipliers, QSOs by band and continent, and off time. Conditions change between years, so the comparison has to allow for propagation, category and hours operated. This tag collects articles on how to build a fair comparison and how to turn the differences into a plan for the next contest.
