Good job Stan!
I'm by no means the fastest person here, but one thing I have found that shaves time is to do the specific lesser/greater clues first.
For example: A is X amount less than B or C is X amount greater D. That helps me eliminate some relationships early on. (I only use that tip if it offers an exact amount though, not just A is less than B). After that, I do the 5 people are, and then go on from there to try and solve the puzzle.
I hope I made sense, but I feel like I didn't!
