Most material removal (wear) occurs between pins and their plate holes, thus pin length / plates thickness also matters (most).
Since I immediately chosed chains with thicker plates (not the 3/16" standard one yet) it was 50% increase of contact surface.
And for the record, after I swapped 3/32" for 1/8", and then again to 1/8" with 3/16" plates, I ride since 3 weeks with a 1/4" chain from the motorcycle branch.
We are discussing different things. I was talking about tooth thicknesses. I just measured 3/32 and 1/8 Campagnolo cogs; dimensions were 0.085 and 0.112 respectively. So actual contact area for 1/8 tooth is 32% greater than 3/32 tooth.
