Note however that different types of input systems were used. Refreshes show the following different types:

  * A slider that need to be dragged to choose a value.
  * A list of numbers shown with highlighting on hover.
  * An input cursor that on hover changes to a list of numbers (within a curved border this time).
  * A text field (enclosed in a circular border), allowing manual input.

I'm quite interested in how results varied depending upon input type (possibly more interesting than seeing how they vary by referrer).
