Scientific Framework v2.4

The Math of
Regret Minimization.

We don't provide opinions. We provide data-driven analysis by calculating the financial friction of every possible path.

The Mathematical Verdict

Regret of Fixing

                                RF = [ Repair_Cost ] + [ Risk_Exposure ] + [ Opp_Cost ] - [ Amort_Benefit ]
                             

RF calculates the total liability of retention. We factor in the immediate bill, the statistical probability of a failure cascade (P_fail), the opportunity cost of capital lock-up, and the amortization benefit of spreading the cost over the remaining utility years.

Regret of Moving

                                RM = [ Friction ] + [ Asset_Burn ] + [ Liq_Loss ] - [ PoM_Dividend ]
                             

RM calculates the friction of replacement. It includes transaction taxes/fees (Friction), the immediate 12% off-the-lot value drop of a new asset (Asset Burn), the spread between retail price and trade-in value (Liq_Loss), offset only by the psychological "Peace of Mind" premium.

Calibration Benchmarks

Constant v2.1

Asset Burn Rate (12%)

We apply a default 12% "Replacement Asset Burn" coefficient to all new car acquisitions, reflecting the immediate liquidity loss upon acquisition.

Equation v1.8

Repair Amortization

If retention horizon ≥ 1 year, repair costs are amortized (Cost / Years), reducing the immediate RF score to reflect long-term utility gain.

Algorithm v4.0

Risk Probability (P)

Failure cascades are weighted by mileage. The logarithmic stress tax starts at 100k miles, adjusting for the non-linear nature of aging assets.
