VI Analyzer control alignment rules

[gizmogal]

Just curious, what is the VI Analyzer looking for when checking front panel control alignment? I'm getting the message "The controls on this VI's front panel are not arranged in a manner similar to their locations on the connector pane (left).  A VI is more self-documenting when its front panel arrangment matches that of its connector pane."  However, the three controls are visually aligned with the connector pane (see below). Is it the fact that the controls on the left are right aligned? Does it look at vertical spacing?

Well, by experiment it must be the right alignment because I tried left aligning the controls and the message went away. I think it's visually less pleasing though, so I'm going to go back to the right alignment and ignore the message.
