Lucy was a mage even before she joined Fairy Tail so i don't know if i can consider her to have the "shortest time being a wizard". Well if we just based on OVA 3 (if it's canon), Lucy probably started to learn magic after the horse cart incident, just that since she rarely used it, her skills weren't polished like when in FT where she actually took on jobs.

While i'll agree on the Loke and Eclipse part, Loke entered the human realm under his own magic and he was the one fighting the soldiers, Lucy was just supporting him, so if i have to give credit i'll give it to Loke.
