"I Can See What This Is!!!" [UPDATED]

KENT-41A8CB

That moment of joy when you recognize a known pattern in the form of a lump of crud:

Kent FLO ‏ @Kent_Finds 21 godzin temu
#FindsFriday this week looks inconspicuous, but this hinge is in fact from the shoulder of a set of 1st-2nd century #Roman Lorica Segmentata and the first piece of imperial roman armour reported to PAS #Kent and first on the PAS DB to include part of the iron plate. #RomanArmy 

[She did not say, it's KENT-41A8CB] Oh, whooppee, so So the Roman army was in UK too, was it? That's a real surprise (not). Is the charm here for the FLO the mere fact that she can identify it? ("You done well") It is indeed "hand made" as the record says under 'technique' and we know how much it weifghs to an accuracy of a tenth of a gramme,but there is zero contextual situation -which is what its archaeological information value consists of. 'Otterden' is not a context. Silly showcasing of individual decontexctuialised items continues. When does the archaeological (not artefactological) outreach begin?

UPDATE 10th November 2018
At the other end of the country, another FLO shares the Kent lady's excitement:

A fantastic section of Roman armour, and the accurate 10 fig grid ref makes it all the more important in terms of spatial context.

I really do not understand how 'X marks the spot' is any kind of archaeological context.

Right. Here's a map, a field near me. A metal detectorist with a GPS has given a super-accurate 10 figure co-ordinate for the findspot of a piece of Roman armour. Here it is marked on a smaller scale map and then blown up.  We can blow it up more, but the FLO, any FLO, is going to explain to us how THAT dot on THAT map is any kind of archaeological context, because yes, its a 'spatial context', its a dot on a two-dimensional plane. But this is 2018 and Kossinna is dead and I would like a FLO to explain to me (as if I were a slightly brighter-than average metal detectorist) why that small red dot by itself in the middle of a field is archaeology. I say its a small abstract red dot that says where a metal detectorist stooped.  So what, FLOs? Any takers?

[To help you all, ten other Roman objects from the parish in database, five of them coins and one (sic) potsherd. Their location is fixed to varying degrees of detail. Some to 1 meter, several to ten, and some to 100. Parish record contains (acc to database search engine) 41 post medieval inds, 17 medieval, and two of unknown date. Their distribution can sketch out where (one or more) artefact hunters have done over the area, and where we have no evidence they've been - but again, so what?Explain, please folks, why that dot on that map is so 'more important' than any other to a degree that it requires a jubilant tweet].
