So it has 4 total speeds?
Really wish people would not post 'false information'. Here is the FACTS - I just tested them
Pushing FULL UP/DOWN makes wide changes, we are talking 5.5mph and 11mph CCC speed
While I was at 11mph (10.6-11.0) CCC I was able to feather the left stick down about 33% for a split second, this adjusted me to 10mph, did it again and it adjusted to 9mph, did it again and it adjusted to 8mph, etc etc.
While I was at 5.5mph CCC I was able to feather the left stick down about 33% for a split second, this adjusted me to 4.5mph, did it again for 3.5mph, did it again for 2.5mph, did it again for 1.5mph
MAX SPEED : 11mph
Major Speed Settings : 5.5mph and 11mph
Finer Adjustments can be achieved at 1mph increments faster or slower
