 The "Regiment of the Leagues" is not very different from the rule of marteloio.The Regiment of the Leagues always considers the west-east bearing as the "intended course" and measures set deviations from it.More specifically, the league table considers a fixed value of "alargar" – set at 1 latitude degree (or, in the measurements of the time, 17.5 (Portuguese) leagues, or equivalently 70 (Italian) miles).
