There are 3 criteria to know when you are done with the SLAM:
Clear water
CC below 0.5ppm
OCLT is 1ppm loss or less
Unfortunately you have not passed the first part which is clear water. There is no need to perform the overnight test for the sole purpose of the OCLT. But you should check chlorine in the morning to make sure you don't have to add more chlorine. Keeping FC at SLAM level shouldn't be difficult if you're not using much to kill stuff.
