1) I'll try to do better but, I think I'm SLOWLY a little better-maybe!?!
2) Must remember any of this type (ceramic tile, composite, applique etc.) is like a "stew" of many ingredients are involved (to include fire retardant features.) to make it all work. The prime ingredient seems to fall in the 10mm-30mm (Against imagine that 30mm to lesser AP type rounds.) 60mm thickness is attributed to tiles that have a special alloy aluminum balls inserted into it to further distribute energy and better defeat the warhead. So that 1"-2" thickness overall plus obviously lighter weight might just be in the ballpark. Most modern (and I suspect DU as well) use Tungsten Steel (LEO/CHALLENGER 2/LECLERC and many others.) which is supposed to be almost (a relative term.) as strong as DU. I believe we again use it to a lesser quantity/thickness
with DU for the ABRAMS as TUNGSTEN IS VERY EXPENSIVE in comparison to the number of tanks involved.
This combination is the edge for the ABRAMS I believe, not a huge one but enough to make a difference I suspect by %. Also we produce/store vast amounts of this material compared to the rest of the world through our weapons and nuclear energy programs as a "waste" by product which DU comes from for ammo and armor use.
3) Same armor tables same source. LEO covers LEO 2A4/5/6.

A note on these tables, they only consider RHAe (Rolled Homogeneous Armor Equivalent) protection levels against KE and Chemical (HEAT) rounds.
