At this rate the bubblepattern is most stable and creates the least amount of surface disturbance.

The liquid velocity is symmetric towards the wall. Values in (1) are 0.3 m/s for the discrete bubblepattern (where bubble rising velocities are 0.7 m/s).
As yet gold's price chart does not display the classic bubble characteristic whereby the pace of increase seems to accelerate (although silver has been conforming to that pattern lately).
