Adaptive Grade Plus

Your legs are burning. How steep is it? Garmin: 3%... Tired of seemingly random and fluctuating grade estimates? Get accurate, responsive slope readings for road cycling. Our data field uses adaptive regression to estimate the grade in real time, smoothing on steady climbs and reacting quickly to ramps. It logs gradient, climbing distance, and more — with display modes from compact to full altitude charts and statistics. Ideal for hilly or mountainous rides, with FIT logging for full post-ride analysis.

v3.1 : Improved layout for x50 devices v3.0 : UPDATE VERSION 3.0: New Simplified Layout - The data field now displays a new layout with a large current grade in the middle - Max grade has in most cases been replaced by the 10 second max grade (eg the maximum grade you have spend 10 seconds at or above) - The field also displays the (up to) 30 minute max grade v2.3 : You can now disable continuous grade logging (default off) and still record session summary information (default on). Bug fixes and more. v2.2 : FIT file recording now optional and futher optimized memory and performance. v2.1 : Reduced memory usage of data field. v2.0 : UPDATE VERSION 2.0: Now includes live statistics of your climbing efforts. v1.5.10 : Implemented additional small layout option showing grade, climb distance and VAM. v1.5.7 : Implemented Edge 550 and 850 compatibility. v1.5.6 : Fixed issue resulting in reseting values when stopping. v1.5.5 : Attempted to fix crash issue on x30 devices. v1.5.4 : Added debug mode that can be enabled in the settings using the phone app. Check description for further details. v1.5.3 : Fixed settings reading bug that could cause crash. Added stat reset to activity start. v1.5.2 : Changed smooth logging to binned logging. Reduced adaptive window length. v1.5.1 : Added sanity check to gradients to avoid extreme values poluting graphs. More lenient stop detection. v1.5 : Updated the sample distance code to account for irregular sample timings. v1.4 : Miles/feet support and improved support for older devices (x30 series). Improved data field settings with additional options. Implemented a smoothed logging option to reduce artifacts in the logged results. v1.3.3 : Improved layout for smaller devices v1.3.2 : Implemented max-grade-logging window-length criteria (must be longer than minimum length) v1.3.1 : Increased font size of values and added buffer settings info to NO DATA status message v1.3 : Added settings to adjust buffer length, gradients and more v1.2 : Implemented adaptive gradient buffer length v1.1.1 : Fixed small data fields not loading correct layout v1.1 : Implemented dropped sample compensation v1.0 : First release of the data field
