This just in from Mr Stark.
Regarding red Osc numbers:
"The red there just says "Hey, this is probably not ideal..." The Osc-index shows the odds that two adjacent guide commands (in RA) are in different directions. On a perfect worm gear with no periodic error, this would be 0.5 -- the last motion not telling you anything about the direction of the next one -- pure noise. As we have PE, the ideal value goes down. Let's say it's an ultra-smooth worm but has some real PE (just not a jagged curve). Well, as you go up the curve, the next one is in the same direction as the last. Same deal as you go down it. The only time you change direction is at the very top and bottom of the wave. The ideal Osc-index would be very low.
For most folks, the ideal is somewhere around 0.3-ish-or-so-kinda. I color code it to say "Hey, you may want to check this out." If your guiding was great - great! If not, it may be that you've done something like reduced the aggressiveness too much.

thats the answer.
