Spectra broke almost always.
Mono on both tests
The knot was breaking in the middle.
Yellow spectra turned white from the first wrap to the last.
Thanks.
OK,,, thanks for that feed back.
Following is my best effort as feeble as it may be I am willing to take a swing at the

Most all problems with the FG results in either insufficient cinching or the
number of wraps needing modification. Cinching appears great turning translucent all the way
the end of the wraps. That is an indication that there may be too few wraps as the spectra leader
interaction has gone very smoothly. Perhaps too smoothly .
Smooth cinching indicates hard very slick leader surface and
or the coating on the spectra which can act like a lubricant which promotes easier cinching.
A little known fact is that spectra on its own has the coefficient of friction very close to Teflon. Which
is one of the root causes of all the knot tying difficulty using spectra. When too few wraps are constructed
the cinching pressure per wrap is increased and in some cases becomes excessive resulting in either the leader or the spectra separating. It is beneficial to construct the max number of wraps so that cinching force
or "Tuna Force" is spread out over as many wraps as possible. The best way to determine this is to keep adding wraps until the last 1-2 wraps will not turn translucent . That indicates that all the pulling forces has been distributed as evenly as possible through the entire wrap.
So my best recommendation is to add some more wraps. Start with +5 and go from there. If the spectra still turns translucent all the way to the end and premature knot failure is still apparent add a few more turns. You will know when the max limit of wraps is reached as the spectra will not go translucent any further as all the puling force will have been absorbed by the previous wraps.. Then just back off a couple of wraps and that will be it.
The PP/Jinki combination resulted in a 69% connection.
The PP/Diamond combination resulted in a 66% connection.
Definitely room for improvement.
All though both are probably "adequate" as drag settings will be way below the breaking points. Which is the main reason less then stellar connections catch a ton of fish.
If adjustments are made please post up with the results. I may have to "adjust" my thinking....!!
My .37 cents worth for your consideration.
