Hi Archereus, I'm the main designer of the sheet and I'd be happy to explain. The second and third scores are reference numbers for player's use. The second number lists how much experience you need to gain to get to the next rank, the third number lists how much experience was required to achieve the current rank. Originally, I was going to make a single experience field dictate the Score but when I polled people, about half liked the idea of tracking 0>next rank (ie, resetting xp score after every rank) and the other half liked to track total experience. Because this sheet updates an older sheet, I didn't want to make assumptions about what method people were using and so I just made it a quick reference.
