smartprobe - configuration questions

If you probe down fairly quickly then probe up very slowly the tip deflection when contact is re-made should be very small.

I don't understand where probing up will make contact. I have tried manually probing Y at different heights using the probe Y function in pathpilot which does touch a second time very slowly. Compaired to the three points with my edge finder, the results were very dissapointing (the plot of the 6 points I struck was near .02 off in radius. I have no idea at what point on the ruby tip the actual contact is being made.

G38.2 probes to the work until the probe internal contacts break.
G38.4 probes away from the work until the internal contacts make. This ought to be fractionally more accurately positioned, more so at very low speed.
