You're right - the list is wrong

Which compact is the blur king? With F-stop equivalencies:
G1X - F3.6 to F7 - 120mm tele
G1X2 - F3.6 to F11 - 120mm tele
G5X2 - F5.4 to F8.4 - 120mm tele
G7X3 - F5.4 to F8.4 - 100mm tele
MFT12-40 F5.6 to F5.6 - 80mm tele
Actually I thought the G1X series would have a bigger advantage here, but as you can see below the G7X3 keeps up well with the best G1X up till 100mm. The G5x2 then has the same range as the G1X-2, so these are comparable.

So it seems the LX100 still is the clear winner and outperforms for example an Olympus EM1.2 with 12-40PRO lens (in terms of DOF control).
But what is the limit? How much lower can we theoretically go in the graph below, still in a compact body? Well, the A7C is a fairly compact full frame camera, say with a pancake 40/2.8 type of prime (a la the existing Canon 40/2.8) it would seem like a dream machine. But Sony doesn't have it. But maybe even a fixed, folding zoomlens (a la G1 design) would be an option? Have they really hit a brick wall yet? Or havent they been trying?
Kind regards,

Your list is not quite right,
G1X, 28-112mm Equiv F2.8-5.8
G1X ii, 24-120mm equiv. F 2.0-3.9
Even you convert the aperture to full frame equivalent, I cannot understand why F number become F11 for G1Xii whilst G1X become F7. I have used most of those cameras. The best background blur (Not bokeh, Bokeh has more meanings than background separation) is Canon G1Xii at the end of tele zoom. Panasonic LX-100 has short zoom. The background separation at the end of zoom (70mm) is not as significant as what we could get from G1Xii. So far G1Xii is the king. Searching the sample photos in the internet, it is not difficult to figure this out.
You're right that the list is wrong - for 1.5" sensor (crop factor 1.92):
G1X i becomes f/5.4-10.8 (FF eq)
G1X ii becomes f/3.8-7.5 (FF eq)
