Advanced Grade is an app that eliminates grade (slope) jumps in Garmin Edge devices. It has many settings for flexible custom setup of the filtering of the grade. In addition it can display the max/min elevation and max/min pressure. All of the selected variables can be displayed with one decimal place. The default settings are chosen to ensure a balance between accuracy and fast response.

Features:
Label
- the title of the datafield, maximum 20 characters.
Decimal point
- when switched on, the selected variables are displayed with one decimal place.
Separator
- the separator between the selected variables.
Grade (%)
- display the output grade from stage 2.
Minimum grade (%)
- display the minimum of the output grade from stage 2.
Maximum grade (%)
- display the maximum of the output grade from stage 2.
Elevation (m)
- display the altitude above mean sea level.
Min elevation (m)
- display the minimum altitude.
Max elevation (m)
- display the maximum altitude.
Pressure (hPa)
- display the ambient (local) barometric pressure, it's smoothed by a two-stage filter.
Min pressure (hPa)
- display the minimum pressure.
Max pressure (hPa)
- display the maximum pressure.

Minmax - Minmax values processing
Settling time (s) [1 - 20]
- min/max values settling time.
- default value is 3s.
Reset on Lap
- whose min/max values to reset when "Lap" button is pressed.
- default value is "Grade".
Grade auto reset
- which grade min/max values to auto reset.
- default value is "None".
Grade res time (min) [1 - 120]
- grade min/max values auto reset time.
- default value is 10.

Stage 1 - Grade calculation
Grade source
- grade calculation source, where "Min (Press, Alti)" means the one whose output is smaller in absolute value.
- default value is "Pressure".
Distance (m) [1 - 100]
- traveled distance, based on which the grade is calculated.
- default value is 40, my advise is to not set it below 10.
Max limit (%) [1 - 100]
- if the grade is higher than this value, it's rejected.
- default value is 30, you can change it depending on the maximum grade you will be climbing.

Stage 2 - Grade filtering and rejecting
Settling time (s) [1 - 20]
- this parameter defines the settling time of the filters.
- default value is 8, my advise is to not set it below 4.
Rejecting mode
- default value is "Max accel".
Max accel (%/s) [0.1 - 10.0]
- the maximum allowable grade increase in 1 second.
- note that if you change the settling time of the filters, the accel may change.
- default value is 1.0.
Wait accel
- time to wait for valid or invalid grade accel.
- default value is 4.

Debug - Additional parameters for debugging
S2 input (%)
- display the input grade of stage 2.
S2 filtered (%)
- display the filtered grade in stage 2.
S2 accel (%/s)
- display the grade accel in stage 2.
S2 cntr valid accel
- display the counter of valid grade accel in stage 2.
S2 cntr invalid accel
- display the counter of invalid grade accel in stage 2.
