When my database of climbs began to grow I realized more and more that I simply have to make choices based on some rules and definitions to get comparable and consistent data: where does a climb start and end, what's the average gradient, how many climbs to the top can you 'onderscheiden'. This meant that 'beetje bij beetje' a kind of structure has been developed from where I have build my data like an atom in material. In this process I had to make choices so this structure is not a 'onweerlegbaar' fysical law but it's debatable. So this page will be rather technical but if you are like me and wan't to compare climbs it's worth reading.
