How we calculate event-music prices
We estimate the professional market while preserving the differences between unlike price observations.
| Tier | Evidence | Use |
|---|---|---|
| A | Direct provider-published ensemble/package price | Primary evidence |
| B | Marketplace provider listing with clear context | Supporting evidence |
| C | Marketplace aggregate quote/transaction data | Calibration |
| D | Professional pricing guide | Context |
| E | Generic editorial estimate | Lowest weight |
What we avoid
We do not treat missing prices as zero, assume every starting price represents a quartet ceremony, or count national network city pages as independent businesses.
