Also, in order to understand how this works, I added age and weight columns to the coin control window. I find it's useful. If you think it's a good addition, feel free to use this patch.
Also, if I messed up on how these are actually calcualted, feel free to correct me
It appears consistent with the total weight displayed in the bottom right corner, at least.
