✅ Midpoint Calculation Gate

Students complete a midpoint validation check in which they individually verify selected ratio and percent computations from their team pricing sheet, then teams reconcile any mismatches and submit a corrected version. The checkpoint focuses on computational accuracy, traceable work, and whether the sales model inputs are reliable enough for graphing and forecasting in the next phase. The class ends with the brief required oral pair debrief about strategy, corrected error, and team organization under pressure.
