fcpx Speed Ramp adjustment only little by little

Hello,

This has been bugging me long enough, time to ask here. When adjusting a Speed Ramp after using Shift+B to select a portion of a clip to change the speed to, if the clip isn't standing alone on the timeline I normally can only adjust a little bit of a speed at once.
Example, I want to drag the end of the speed ramp section and go from say 100% to 900% just by dragging. When i click and hold and drag left it will only go from 127% to 142% for example. Moving further left past the clip doesn't do anything either.

What am I missing?

Also I wish speed ramp changes like this would snap to markers with snapping on.. Bug in my opinion.
thanks all,

Try zooming in and out of the Timeline pane. Your zoom level can affect the sensitivity of the mouse cursor.

You can move a speed ramp past the end of the clip it is applied to, that's physically impossible.
