# Advanced experimental design

:::{admonition} Placeholder — not yet written
:class: note

The full recipes are coming in a future release.
:::

This guide will cover the design choices beyond the defaults: custom
round-size schedules (your own `Schedule` implementation in place of
geometric doubling), custom graduation rules for when a treatment
ships or stops, and cell-weight strategy — how much traffic to hold
in baseline and exploration cells versus the targeted allocation. In
the meantime, the
[first adaptive experiment](../tutorials/first-adaptive-experiment.md)
tutorial shows the default design end-to-end.
