We increase these time-different survival scores to fit the specifications of 4 separate LGD designs - Tobit regression, choice trees, Logit-reworked linear regression and Beta regression.
The scores confirm being strong decades into the long run without measurable degradation in efficiency due to the stabilizing impact of your offset component in the course of product design.
