A Question about WatchUi Layers

 I would like to display a steps count every second, ie most probably in onPartialUpdate (I'm aware of the constraints on using this) in a similar manner to the second hand in the Analog sample.  However, when I try and do this the count then sits over the hour and minute hands (but not the second hand) which I assume is because the minute/hour hands are only updated every minute whereas the steps count (and second hand), being updated every second.  Would it be possible to use layers to ensure that the steps count lies lower in the layer stack (is this what the layer.height attribute is for [ and does it start at 0]) and thus under the hands, even if updated more frequently?
