Actually, the implementation also uses the trick described in "Solving Thue equations without the full unit group", Math. Comp. (2000) in order to avoid as much as possible calls to bnfcertify in large degree. The strategy is basically Baker's method as described in Tzanakis and de Weger (JNT 1989) seminal paper, with significant algorithmic improvements regarding the bound reduction and final enumeration steps.
