How tall is that loop?

Does anyone know how tall Superman: Krypton Coasters loop is. Different websites say different things.

OK, Coasterbuzz says the height of the coaster is 142'. RCDB says 168'.

I have heard S:KC's loop is as tall as 160' and as small as 135'.

Why is this ride shrowded in such mystery? I mean, how tough is it to measure the height of a coaster's loop?
