When I re-fix the Excel formulas, the formula I'm using for Profitability is the same as yours: $$ProfitabilityPerHour = {TotalIncome - (0.072363293 \times RepairCosts) \over IncomeHours + (0.072363293 \times {IncomeHours \over 2})}$$ which simplifies down to $$ProfitabilityPerHour = {TotalIncome - (0.072363293 \times RepairCosts) \over 1.0361816465 \times IncomeHours}$$
