My environment with one-click 75-lines is show below.
 - Logitech Anywhere Mouse MX
 - MacOS 10.9.5
 - Logitech Control Center 3.9.0.
   - Speed: Slow
   - Acceleration: Middle

Its wheel is similar to Logitech Performance MX mouse as described by
Kaushal.  It seems that `one-click' on the device generates several
`typical one-click’ considering velocity.
