Topic: lower shrouds different lengths?

Hello all

I pulled the upper and lower shrouds from the mast today, to have them replaced and noticed that the lower shrouds are different lengths. if I recall correctly(I have them marked some I don't have to remember) the aft lower shrouds are shorter than the forward ones. Does this sound normal? Can anyone come up with a reason for this other than just because? Not a big deal I just find it curious that they are not the same length.
