Hi Stuart,
No speed information seems to show up on the data graph for the RS200. The speed axis itself does show up (with sensible limits) and in Graph Preferences I have ticked "Heart Rate", "Speed", "HR Zones" and "Lap Averages". This used to show the average speed per lap a long time back when I first started using the beta versions, but seems to have disappeared at some point (don't remember which version). The heart rate lap averages are plotted perfectly fine.
A much smaller issue: when speed is set to min/km, the exercise summary below the data graph gives "Speed (Max) 20:00", which is the highest value but the slowest speed.
Regards,
Tom
