Abstract The magnitude of the vacuum expectation value of the Gukov‐Vafa‐Witten superpotential W0$W_0$ plays a central role in the phenomenology of type IIB flux compactifications. Recent analytical constructions have shown that perturbatively flat vacua can be used to obtain very low values of W0$W_0$. We present systematic algorithms to carry out exhaustive numerical searches for such vacua. We also analyse them in the statistical context, as part of the entire ensemble of type IIB flux vacua at low W0$W_0$. Our preliminary analysis indicates that these perturbatively flat vacua are statistically sparse in the whole set of vacua at low W0$W_0$ as calculated by Denef and Douglas. Two‐moduli examples are used to illustrate these more general findings in specific settings. We find that these simple (two moduli) cases are good examples for existence proofs but they do not feature a large statistical tuning freedom for phenomenological applications.
