Great information. What got my attention is the change once you were at the deepest water depths. If you combine some of the numbers there is a signifigant differance:

00-06': 8.81 avg.
07-14': 9.31 avg.
16-25': 9.47 avg.
30-40': 11.65 avg.

The weights stay almost consistant until the the 30+ range then a two plus pound increase. May have to change my ways.
