Distance certainly could cause jerkyness, as it has a spasmodic connection.
Bluetooth does not have a long distance reception.
Does it stop being jerky if you move the mouse closer?

Are you using a 5GHz Wireless Network or a 2.5GHz wireless network?
If you have installed any mouse add-on, uninstall it, especially USB overdrive
(uninstall not just remove the preference panel).
Check a few other things you could try changing and then test to see if it
helps.
1. Choose System Preferences from the Apple () menu, then choose Mouse from
the View menu.
Set the Tracking slider to adjust how fast the pointer moves as you move
the mouse.
2. Try using a different surface to see if the tracking improves.
3. Turn the mouse over and inspect the sensor window.
Use compressed air to gently clean the sensor window if dust or debris is
present.
Bandwidth intensive devices could also affect tracking.
Cheers,
Ronni
