Asking for a new datafield related to hill/mountain grade %.
It might be very very similar to Visual Speed Alarm, with Grade % instead of Speed (cloning should be almost total).
5 grade zones, configurable medium value with offset, different colors, possibility to set an average on seconds.
Even better if possibility to setup each grade zone (similar to Visual HR Zones).
Such a visual grade % representation is very useful to identify at a glance the proper gear ratio to set depending on the "coloured" grade zone.
Many thanks in advance to whom will implement such a visual datafield.
