Everything is read from public sources and computed the same way every day. The floor, the trait floors and the premium are read, not estimated. The per-punk valuation (beta) is the one estimate on the site: a number and a range from past sales. How the valuation works.
The floor is the cheapest punk anyone can buy. CryptoPunks has its own marketplace built into its contract, so we read it from there: we replay every listing, sale and transfer since 2017, and for each day take the lowest asking price left at midnight UTC.
