Friday: Data packing

Why would you ever pack data into an array such that for a variable length set of X_i, each of which contains a set of x_ij, would you ever pack things x_00,x_10,x_20,x_01,x_11,x_21,etc.?  That is the least intuitive way to put things together, since the location of each element of X_i is separated by the number of X_i that exist.  Because of that, today was largely spent like this:

Basically just guessing how things are arranged to figure out what's going on.
I still don't believe my results, either, which is always wonderful.  Grumble.
