Borrowed Example 2 structure; calibrated weights produced 7 percent variance.
A Series B SaaS team was running single-formula projection on borrowed stage weights. The RevOps lead rebuilt projection using the Example 2 structure (four formulas, trailing-4Q calibration, risk subtraction) with weights pulled from the team's own conversion data. Within two quarters, projection variance tightened from 18 percent to 7 percent. The structural borrow worked because the calibration step was done carefully; teams that borrow the structure without calibration usually see less improvement.
