Sub 5 hour is likely possible. Need Treasure Hound, Thrifty Transit, and Swift Shoes (maybe not) as active kupowers. Need to run on Sunday morning "Gain Experience" RoE for 2x Vana'versary Objectives for free 5.5-6.6k exp after weekly reset. Need great RNG on Bee Pollen, Gausebit Grass, Coeurl Meat, Fetich Pieces, and during levelling. Should be attempting Shadow Lord at Lv. 48 unless perfect run prior to the fight. It would have to be the absolutely perfect run lol
