I rather learn your way which I can actually understand.

So let me give this a shot

The S_1,S_2,S_3 are basically the T_1,T_2,T_3.

Then we get the formula you got.

Next we plug that into a venn diagram

Is this venn diagram containing three circles one for each S_i.

Therefore the middle of S_1 S_2 will be shaded plus S_2 S_3

This shows that S_2 must be greater than the other two.

Is that the logic.
