Notice that the peak of solar cycle 24, which we are currently in, is nowhere near the peak of solar cycle 23. Then, compare that to what was predicted. According to NASA, cycle 24 should of been at least as busy, if not busier than cycle 23.
So, the question is: with NASA's prediction that the peak of solar cycle 25 is even lower, do we believe it?
Was it so wrong about solar cycle 24 that we throw out the prediction? Or do we believe the trend that it will go down?
Another wild card is that some scientists are thinking this current solar cycle may see a secondary peak early in 2014. Notice, in the second graph above, the recent trend was that there was a second peak (cycle # 20, 21, 22 and 23) while cycles #18 and #19 did not. The thinking is that #18 and #19 were strong, while the others were not. The fact that this solar cycle is weak plays a role into the thinking that a second peak is possible.

No, it means the model is broken. The solution is to fix it by examining other relevant data :P
(Keppler for example is so busy looking at other planets around stars that NASA is ignoring the stars themselves. The question should be, "What do other G-type main-sequence stars tell us about our own sun?")
Peace!
