ok so the facts are GUR max is 39999 & your Santa Oracle's ATK and DEF stats are @22k...

ATK & DEF stat: 39999 - 22000 = 17999

17999 divided by 50 (since arcanas is +50) = 359.98 (360 arcanas each)

720 ATK & DEF arcanas x 180 medals per arcana = 129600 medals

Conversion Factor: 2.5k medals = 1 day

129600 medals divided by 2.5k medals per day = 51.84 days

Not good either lol
