I was Looking over  Google Webmaster console and saw this recent addition to the interface.  It's intriguing because It shows a variable position.  Everyone, well most everyone has been assuming static positions in the SERPs and this clearly demonstrates that it's being moved depending on some unknown factors. Without a time factor is hard to determine what it all means but this does throw a new spin on Search Engine Optimization.

This is an intriguing tool if it stays 'on'.
