Limits RegistryPUBLIC RECORD
Limits RegistryThe Australian wedge-tailed eagle (Aquila audax) has the highest measured visual acuity of any animal, about 138-142 cycles per degree - more than twice the typical human limit of about 60 cycles per degree. Its acuity was measured in behavioral grating tests by Reymond in 1985.

Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
