This question relates to about Step 2 of Auto-leveling, but what is a typical extrude/probe offset along the X-axis?

I know that there is no single answer to this as there are a host of manufacturing variables in the sizes of servo and probe components, but I feel sure that there must be a typical ball-park figure.

I got my measurement by adding together a number of distances (extruder to probe arm; width of probe arm, and distance between edge of micro-switch and centre of its button)

I got values ranging from 30.65 mm to 30.71 mm. There is some lateral play in the arm. Looks like 30.7 would be a reasonable value for my machine.

When I enter a value for this offset, how accurate should the value be - to the nearest 100th; nearest 10th, or nearest unit?
