Best companion

Pair it with [[The-Bias-Variance-Tradeoff]] when you want the cleaner baseline before stepping into the stranger double-descent regime.

Time and level

About 12 to 18 minutes. Intermediate. It lands best if you have already seen standard overfitting stories and want the weird edge case next.
