54.017, so double it because of the sp ticket which is 108.034 sp over whole lvl 88.
But the thing is..With a prem+ you have 2 hours more gt than your sp ticket which means you won't grind the whole lvl with double spx. So reduce a few k's from the 108k and you should get like 80? or 90k total in 88. Unless you grind even outside of your ticket which would mean you would get even less
