Use the original nMonte over nMonte3 if you aren't already, nMonte3 tries to remove outlying coordinates within the average and gives results +/- 30% different give or take each run. Completely inconsistent and useless, while nMonte1 gives pretty much the same results each run within 1-3%. Better to just use individual coords in nMonte1 rather than averages and let R remove outliers rather than nMonte, if you want what nMonte3 was supposed to be able to do(removing outliers from averages, finding extra specific genetic drift that may only be in some individuals). Shame nMonte runner removed the option of using nMonte1, for free users anyway.
England_IA had too much mainland Celt(clustered south of English), the Anglo-Saxon samples were already mixed except 2.
This is my go-to model for British Islanders and NW Euros. DEU_MA is split up into individual coords because Davidski actually left in 2 outliers in the average, one Finnish/Balt admixed, one central Euro, and using the average inflates insular British or local Beaker by a lot everywhere. Only natives from Sigtuna used. Honestly, every pop should use the individual coordinates rather than averaged, people are just too scared of overfitting, for no reason. The 4 Bavarian_Beaker(and the Swiss Beaker average, the Bavarian beaker average has too many northern beakers) are what I think to be mainland Celts and the main population around the Alps pre-Germanic/Roman migrations, nMonte prefers them over Hallstatt(only 2 samples which both clustered very weirdly, one clustering with no moderns way west of France, one supposedly had some Scythian, probably population dead ends) for nearly every population, but I'll also include a model without them because it is pretty speculative, although I'm pretty confident that's the case.
So, 59.3% insular Brit, 32.5% Germanic(22-25% is closer to what I thought and got using worse models, but it definitely isn't 5.6/6.6 like those first two models), 10.2% mainland Celt.[1] "distance%=1.1779"

As for this whole British admixture in Norway thing, keep in mind there's 2 Norwegian samples in the database all geneticists have access to. One from West Norway, in Bergen, the other from Oslo. We have absolutely no idea how large the sample sizes of each are, or which they even used. I know on G25 the Norwegian sample is both averaged, but the sample from Bergen could have an N of like 250 and the one from Oslo 25, we just don't know. This British signal does show up in G25, and it's not really surprising, but you can't really know the % for the whole country.

People have been speculating Bergen is extremely British derived for a long time now to explain why Bergen is so dark, and just look at this hair pigmentation map by Swedish anthropologist Bertil Lundman:
