Fail to understand the test old tanks as used in the videos so I know they should go bang pretty often run the same test on Abrams Challenger or Leo.
Bear in mind as said game does not model damage to secondary equipment.
I would consider a tank that is hit losses its TI FC RF & maybe a weapon so it is less effective than a WW2 tank to be destroyed for game purposes.

Its hard to tell because the tank completly disapears even in slow mo but lets assume the tank is roughly in the centre of the strike which is about 3 times the size of the tank.

The central ones hit it on the top with a good chance to damage.
The others nearby fall around it so will hit front side rear with varying degrees of success & angles.
Ones on the perimiter just provide a blast wave no effect unless its a soft target.
Consider the top ones a direct hit the others a near miss type thing

It would be intresting to know the Db noise rating in the tank the crew could well be shocked.
Say a dozen hit it virtualy simultaniously plus the shock wave of all the near misses total crew disorientation seems possible.

On the total blast as in shock wave it looks more powerful than a regular arty shell blast probably because a lot of it is airburst rather than being absorbed by the ground.
