This is little bit advanced. For purposes of level 1 research model, this whole is a new decision method with new class of decision makers. As much as I know nobody is using this method.
This is not research, this is advanced application. See research fist.
Model is mostly chronological. Links that would make the model messy are left out.
Some more notes... GDI is good decision index in percents of "Yes, back in time, I would like the decision to win in comparison again." GDI feedback may start right after decision, but should be editable. Other feedback may be directed almost from any place to any other, here we got just the one qualitative loop that is of high importance for this explanation. Request for method may be resolved by many methods, GDI tells very little about it. Priorities might be different e.g. there might be not enough time for some method, there might be preference for socializing or learning, "uninportant decision do not need to be that much good", etc.
