I remember reading of an Ozzie on Redditul that froze on this mat (remember last winter Zapruda?) but I think it was his quilt that was the issue.
Had you done all the necessary things like:-
-eating something sustaining before bed,
- ensuring your quilt was up to the task. Sealed all round, appropriate amount of down.
-good pjs
etc,etc.
GG thinlight on order for you maybe-or nip into Clark Rubber for a 3mm (?) mat to put on (which I would do for the heavily open ridged Klymit) or even under your Klymit?
One of the forum members I recall, feels there's no difference and I myself would heed that advice normally, but, for the Klymit given its open structure, on top might(?) be better.

BINGO! It's the quilt with it. The mat simply does not work well with a quilt.
I sold my -12C Tier Gear Quenda as a result...although perhaps I should have sold the mat?!!
I used the Klymit UL V (Massdrop) mat all last Winter and the lowest temp I got to was -1C, using CCF underneath the mat and my space blanket groundsheet. Even wearing wearing all my clothes,beanie,warm buff etc etc I still froze with my beautiful big quilt. The mat works much better with a bag, I switched out to an Aegismax -8C (M2 orM3 I think?) bag after one too many nights freezing my bits off and was much warmer for it.

I think it will also depend on your weight and how it compresses against the ground - softer might give a more comfortable on your body but might be slightly colder as you have less insulation between you and the ground.
The mat has nothing to do with what bag/quilt you are using.
Back in the '70s there was a US chart showing the temperature to thickness of down insulation (this was back when the US$ was much less than the Aus$ and many of us were buying the gear from over there). It was very useful and one could estimate what bag you needed for a given temp.

First time I’ve used my ‘Klymit Insulated static V’ in the almost cold over the weekend. Temp was in the low single digits, small Icey breeze with windchill. Same quilt, shelter, etc as used previously with my exped synmat UL7. However, any pressure point got slight rising cold which makes me nervous to use it deeper into winter. The exped I only got cold when a knee or arm dropped over the side and sat on the ground, and I was confident in its warmth to just below freezing (puncture resistance and baffles are a different story, hence the klymit)
Some of their marketing suggests the ribs are for your bag to loft into, however being a quilt user this doesn’t come into it and I wonder if it’s where the problem might be? Looking at it, there is lots of points that there would be no insulation, and I really don’t get how they get their ambitious R value.
On paper my old exped is R3.3 and the Klymit is R4.4

You would be okay in high single digits I reckon, of course accounting for all other variables like decent quilt, full belly of food etc, decent baselayers etc. It was only as those single digits approached freezing that I had frozen-MsMudd-in-a-tent issues with the Klymit CCF/Space blanket combo. I think if your quilt is wide enough it should tuck nicely around you. I think that was one of my errors too when ordering my quilt, although I am a small person, I should have opted for a wide quilt for just that purpose. So it may not be all the Klymit pads 'fault' that I was so so cold using the quilt with it.

By day 3 she had ordered a Exped Winterlite, which was the one I used in the snow and on the cold ground with a quilt, on the AT last year. Thick and insulated and never felt the cold even on snow. Owned it 3 years and never had a problem, going by comments about exped mats, I must be lucky or something.
