I posted the a thread on the RepRap forums and promptly got the following reply.
On the 'normal' stepstick it would be the left pad and upper right. If your multimeter supports measuring resistance, you might want to use that to determine how far the trimpot is open.
Ironically enough the person how replied was (or at least seems) to be the same guy who runs RepRapWorld. Which I purposely avoided due to the questionable selection of parts in the RAMPS DIY kit.

By attaching the multimeter in resistance mode to the highlighted points (see above image) on the new
StepStick then comparing it to be resistance one of my RepRapWorld StepStick I was able to match the settings.
For this reason I would avoid snipermand for StepSticks as it adds another step to the set-up and would be even more tricky if don't have a StepStick with a ended trimpot as you'd have to calculate the values.
