Carcassman,
Non-treaty vs. Treaty land would have to be also adjusted to take into account how the current development impacts or helps the current tribe. In other words, what percentage of hospitals, roads, stores, schools or other development are beneficial to the tribes current or past standing. This can become quite burdensome, because the current levels of population are obviously being exploited by the tribes through their economic enterprises. With no population here, there would be very limited use for the timber they are harvesting, there would be no one to visit the casinos, no roads to take fish to harvest, no need for gas stations. Economic standing of the tribe must be taken into account in the current situation, as it is clearly related to the development that has impacted their fisheries. If you take away the development both on and off reservation and add the resulting fish, you then can start reducing their overall economic standing.
