You just told that all that was was confirmation bias on your end…
So what?
Stingers have 0.5kg warheads. Planes often survive multiple direct hits from even bigger warheads with next to no damage to the plane and flight performance.
There have been multiple times where i directly hit a plane (even in the cockpit) with 155mm HE and it did not die, er one lucky hit on a Spitfire (IIRC) with arty strike, and you guessed it, the shell exploding 1-1.5m from the pilot did not kill it.
Or when an F8F casually took about 50-70 pieces of 76mm HE-VT from my SKR-7 and still was able to manouvre fine enough for about 3 kilometers to still bomb me…
None of those planes were russian btw.
Yeah, blunt nose APHE has better angle performance…
Just like NATO autoloaders.
And before that the Schanrhorst did that.
Same with US and german tech trees.
None of those were the best, certainly not the Pantsir.
NATO ammo being taken as gospel while it is proven that it does not exist khm khm L23.

So when ROMOR-A on a Chally lower plate eats DM53 from an L55 gun, does it mean UK bias?
Was it reported? Is that source declassified and also not export restricted?
Are their effectiveness being open to public?
Also you will aim for weak spots anyway, so they could literally just make every compotite/NERA 100x better and nothing would really change.
So what?
Source?
WOW a bug.
Also a counterexample is the Leo 2AV at release with the armor and weight…
Source?
Source?
Just like it can do it now. Learn to aim.
KV-85 top speed took 2 years to fix when it was about 10 km/h less.
P40 is bugged for about 2 years now that makes it even stronger, and they actively delete bug reports on it. Not closing the reports, deleting them.
So what?

You just cherrypicked 10-10 examples. If you would collect every single inaccuracy, and if those support your “pattern” then it would be something.
Tho that would still not prove bias, as it is just an observation.
And it seems that energy generation in Kosovo influences how many movies Will Smith appears in, or vice versa:

IS-2 still having an armor hole for 2-3 years or so…
Yes it is bias. Not russian bias, but confirmation bias on your end.
Because they are different things.
Why does a broken leg not cause the same effect as a headshot wound?
They were added because trash players cried that they dont get an insta kill when they make a bad shot. So they made the same area more voulnerable for both russian and (some) NATO tanks.
IS-2 as an example. Or the T-80 (light tank) had the wrong crew member assigned as loader causing it to have a longer reload than it should when it was on 2 crew. It was only recently fixed while it has been like that for years.
