RHY.7:5.4 - Equal endpoints, different usable peaks

Two constructed four-second sound-control envelopes begin and end at level 0.2 and reach level 1.0. Each follows straight segments between its specified points. A reaches its peak at 1.5 seconds; B reaches it at 2.0 seconds.

The receiving construction requires the peak by 1.75 seconds. Comparing endpoint levels and peak level leaves a tie; comparing peak time selects A and rejects B for this condition. Retain the specified courses for any later question about their rates or intermediate values.

This settles a property of the proposed envelopes. Whether either realized sound provides a usable cue to the intended listener remains a different comparison.
