Ever wondered how to get the most accurate data from your GPX files? Whether you’re a runner, cyclist, or hiker, a clean track is essential for precise performance metrics. That’s why we’re excited to announce our new video guide on using GPX Doctor, a powerful tool inside the Cronzeno app.
In this video, we’ll walk you through two key functions of GPX Doctor:
1. Adjusting Your Start & Split Accuracy
This feature uses the Max Acceptable Distance (MAD) to define when a point on your GPX track has officially crossed a sector line (start, finish, or split).
Here’s how it works: When a GPX point gets close to a sector line, the app measures its distance from the line using a perpendicular projection. The MAD then acts as a filter. Only points with a distance less than the MAD are considered “candidates” for marking the crossing of that line. The app then evaluates these candidates to determine the best one for an accurate time stamp.
Changing the MAD effectively increases or decreases the number of candidate points, which can be crucial for accurate timing, especially for races with a tight finish or closely spaced split lines. We’ll explain how changing this value can either improve precision or, in some cases, invalidate a less-accurate file. It’s all about finding the right balance for your data.
2. Cleaning Up Your Track
Learn how to easily delete a range of points from your GPX file. This is perfect for removing any off-course detours or accidental recording before or after your activity. Remember, this function is for visual cleanup and will not change your recorded times or distances. It simply helps you create a clean, professional-looking track.
