L28’s nose is flat，A flat nose should not have excessive vertical penetration depth
as is visible from your document the Tungsten Carbide Core has a conical Tungsten alloy nose which removes the disadvantages of not having a pointy nose in the tungsten carbide core

What does the 2nd image show?
Also let me just point out that Russian blunt nose rounds receive no penalty for their blunt noses when compared to other uncapped AP rounds.

Results from Soviet Testing of Captured M60A1, under their Criteria.
Though, the L52 numbers are very likely low, due to the difference in penetration method between the tungsten carbide core of L28/M392/DM13, and the Tungsten alloy core of L52/M728 and the way Soviet Criteria at that time worked.

But as far as I know, DM13 can only penetrate 250mm of vertical armor at 800 meters
Perhaps NATO believes that DM13 cannot penetrate the small angle area of T62 turret
Can you provide the document name?
thank you very much
