Details are attached.
Of course, we've done this manually, but haven't automated it -- yet.

Thinking about some tweaks to the system:

For small amounts of slide, the amount of forward/reverse motion scales as the square root of the slide distance (and therefore time), so it should be beneficial to work out how far you're going before you start.

Also, you can slide twice as far with a 1/3 increase in time, by doing L- R- L+ R+ to go right, or R- L- R+ L+ to go left. This technique would also allow all of the distances to be equal, simplifying coding.
