Offhand, I don't see anything that looks overtly slow in the code. I wish you'd have presented this as a function with clear arguments/return values so I could throw some Real Life data at it and see how it behaves.

At times, there's loops nested three deep to do your processing. For me, that's an optimization red flag saying "you're probably going about this the wrong way." Is that necessary? Is there a way to approach this without the looping? (Again, I wish we had a function and some data to play with.)
