my reasoning for these rankings is that well

1. Laxus beat Jura,

2. As Natsuman incorrectly quoted above, during the fight between Laxus and Jura, Makarov noted that Jura's and Laxus' powers were almost as strong as Gildarts' (I'll find the link later)

and

3. As seen here the ten wizard saints aren't chosen in terms of pure strength, rather im guessing because of their prowess in the their magical abilities which doesn't necessarily make them strong (a novice in death magic could most likely kill a master in healing magic) so just because Jura is of a higher rank in the TWS doesn't necessarily mean he could beat Makarov in a fight, also I don't think it means that a TWS could beat any normal or S-class mage that wasn't a TWS.
