I think it is considered standard precision in military aviation, but it does indeed sound very precise to us normies.
I remember watching a documentary about the assembly of the first Hürjet prototype, and the Montage Manager had mentioned that they were drilling 2,500 holes into the wing with a permeability sensitivity of 25 µm (microns) in a 0.1 mm hole (more or less equal with only a tiny difference of 0.4 µm). So, although it is a standard procedure in aviation, these are indeed really tight tolerances for us.
Starts around the 10:30 mark, shockingly the auto-translate in English is actually comprehensible:

This minus is very annoying, because some of the features of those aircraft are in advance of 5th gen, others don't match; since such planes don't stop to appear(and what does 6 gen minus means - 6 gen but with canards, or non-stealth with 6 gen electronics，or what?).
I'm personally inclining more towards broad "2nd day" category; i.e. a type of workhorse multirole fighter, specified by lower maintenance requirements and higher payload carrying efficiency.
In this case, 2rd day fighter really covers anything not meant for high altitude operations in denied airspace. Regardless of generation, and probably regardless of specific level of stealth.
Like in the past, there could be a day fighter of 2nd, 3rd or even 4th generation(original YF-16 ... and probably F-16 itself, until AIM-7/amraam). Or, technically, there *could* be a pre-5th gen stealth fighter(F-117X), it just wasn't born. Or which generation of fighter was Sea Harrier mk.2?
Generation, as a term, implies certain period of time, or certain technology. KF-21(or indeed TEDBF) are of course the worst offenders here, but Gripen E/F is also somewhere around, as is Tejas Mk.2. Too much incoherent, inconsistent minuses and pluses(4.5? 4.75? What next, 4.875?).

Don´t forget that Russia still had S400 in Ukraine a couple hundred days past the 2nd... 
But I can understand that approach. It makes somewhat sense, apart from the strong emphasis on something we know is an unrealistic scenario. Why not simply call them what they are: a 100, 200 or 500 nautical miles generations...
Don´t want to be hard. Semi-Stealth makes sense and is relevant when you can afford qty and attrition. Ukraine could probably have win the Air battle if they had a couple of hundred Mig29 and the pilots that goes with it .*
*That´s why I am furious French President, Mr Macron, dilapidated the french air force aircraft reserve of... a couple hundred of Mirage F-1 that would have stood the fight nearly as much as Ukraine owned Russian derelict Mig29s. Qty matters.

Yeah, day here is more of description of operational environment.Don´t forget that Russia still had S400 in Ukraine a couple hundred days past the 2nd...
1st day can maintain controllable loss rate against active SAM network, and can operate continuously over suppresed environment. It is, however, unavoidably hampered by the requirements of this capability.
2nd day can maintain controllable loss rate over suppresed environment, and can operate continuosly outside of effective enemy SAM coverage.
There may be better term, just not five minus, pretty pretty please.
