No log handy? Try a synthetic underboost example or a real log with insufficient data:

The first is generated data showing how a requested-vs-actual gap is calculated. The second is a real dyno log from HyperTuner, shared under its MIT license, with no requested-boost channel — it shows why the tool declines to judge without a target.
