Your information is rubbish and in accurate.
ten years ago on tank net we were speaking with a Cyprite tanker who had just recieved T-80U from the Russians. They were told explicitly by their
russian technical advisors that while their K-5 armor covert tank was immuned to penetration from the M-829 it could NOT stop the M-829A1.
I spoke with a German ballistic scientist about those German tests and he confirmed that the 120mm DM 53 was able to defeat any K-5 covered russian
tanks at any range they chose to engage.
I'll let you in on a secret. Spaced plate armors and flyer plate armors have been shown to be able to reduce penetration based on rod diameters. But
the strength of the rod can counter act this and the sectioning of the warheads can truncate this effect. THe 120mm DM-53 has both technologies as
does the M-829A3, while the M-829A2 employes n the strengthened DU rod material.
All tank designs are a comprimise and you can't design them to be immune to all threats from all angles, so all tanks can be defeated. You just have
to know how and were. Back a few years they were testing a teflon shaped charge that didn't detonate ERA type armors instead cut a whole through them
to allow the follow on main charge to cut through the main armor.
THe Nosh armor is intreging, but even that can be defeated.
