Agreed. I think the confusion comes from going from steam to digital and giving a wishy washy explanation about how to actually fly the airplane (it's in there but you really have to look for it).
With steam gauges there is no amber band so they created a load of arbitrary (+20, +40, +60 etc) recommended speeds which are easy to follow (unlike the flap maneuver margin chart). They were designed to allow you to safely pull speedbrake at UP,1,5&15, warned of buffetting at F20 (clue!) and prohibited its use at F25/30
When they went to EFIS they had a dynamic amber band which graphically represented where your maneuver speed actually was, which is usually significantly lower than the old recommended speeds and they even included a statement that during normal operations the target speed should be above the Amber. 90% of people refused to let go of the past and stuck to the old way of doing things, rendering the amber band almost pointless, other that as a tool to scare themselves with.
