Horalis Recherche
La fiche derrière chaque méthode : ce à quoi elle répond, sa formule, ses sources, ses tests et ses limites.
Chaque méthode que Horalis utilise, fiche par fiche. Chacune dit à quoi elle répond, d'où viennent ses données et où elle cesse de valoir.
Pour l'instant, les fiches sont en anglais et en espagnol : chaque carte ouvre la fiche anglaise.
