I checked in on 2010-11 CHIP recently and discovered some large disparities between team and division totals.

CHIP was developed by LW3H from Springing Malik, and he updates the current season CHIP value at the end of each month. His definition of CHIP:

The concept again - multiply each game missed by a player by his 2010/11 cap charge, then take the aggregate of these figures for each team and divide by 82. This indicator of value lost to a team by injury/illness is called CHIP (Cap Hit of Injured Players).

He's also done a three-year analysis of injuries, calculating combined CHIP from 2008-09 through 2010-11. He's got enough data logged that some enterprising young blogger might find some solid correlations in there.

LW3H breaks down the injuries by year, by division and by individual and comes to some interesting conclusions:
