It should stay a 10.
Endurance wise, it's really fairly easy for a 10, the only really difficult parts are the twists near the end, but otherwise the song is very simple. The large 7 beat rest in the middle of the song also takes away from the difficulty.
The step count is a little high (596), but other 10s that arent questioned (Hybrid, for example (633)) have greater amounts, so I dont see step count pushing it to an 11 either.
