Wow, you can. but it takes 20 runs to level once from 998 to 999. 300 energy.

Each run costs 2min 30 seconds max if on auto and includes connection to server time.

Approximately 16 Days Max to level from 500 to 999. If it ran straight.(approx 9258 runs)

SKD level up Guide (All credits to Eleiryn)

With SKDx4 you should be able in less than 13 days, even with Zelnite at 10% exp boost (still not enough time, but will raise it enough to being prepare to hit 999 on the next SKD).
