How do you just adjust the right hand edge while maintaining the level ?
On a 4 point system you simply adjust both right knobs the same amount.
On a 3 point, if you adjust the back knob abd right knob the same amount, you actually end up tipping the plate backwards. If you jjust adjust one knob it tips in that direction. To get any kind of consistent levelling is bloody difficult.
