> Hopefully the effect is becoming obvious - by impacting the statistical armour and detonating at that point, the armour has given the RPG a free c.300+ mm of free standoff extension. The armour just amplified the threat capability by a good 20%, making life worse for you inside that vehicle.

For an APC with ~5cm of armour, pretty much any garden variety shaped charge will penetrate it with ease. If the chance of penetration is already 100% it doesn't matter if the charge is 20% stronger. But having the cage at least gives a small chance of stopping the charge from ever detonating.

Different story with tanks though, where the extra 20% could mean the difference between a badly damaged hull and the complete destruction of both tank and crew.

This kind of additional armor is usually on the rear, which is much less protected. In fact it wouldn't make sense to put them in front of a piece of armor thick enough to survive and RPG shot by itself. So in practice this extra 20% would never change anything?
