Data are reported for change in variables from first to third trials with respect to time per tool placed. Variables of interest with respect to time taken per tool placed: number of tool touches, mean time taken to grab and place a tool, mean distance travelled to grab and place a tool. The time is measured in seconds and the distance is measured in millimeters.
