Amir, I don't see the issue? It looks like the software is simply rendering the primary frequency in a tight line. If you really think there is something badly wrong why don't you ask for a zoomed in version of the chart or clarification of the result instead of calling into question the credentials of someone who does this sort of thing in professional capacity based entirely on assumption and speculation?
As for the rest I will refrain from commenting as my understanding of jitter measurements is limited to looking for obvious spikes and that a narrow jitter band is better then a wide one. Using those two metrics the Yggdrasil performs very very well.
