200 Watch - ETAs for GMS

eos i was reading your last update and something is really strange, is that even possible?:

Gentle
Job: Magician
min: lvl 131
max: lvl 187
average daily exp: 7,566,383,038

i know you just get the info from rankings and theres nothing you can do, but this already happened before? could it be a GM test char or something or is just a bug? =o

i am pretty sure 7.5b exp day is impossible without 8x , maybe even with hacks
