Going higher than the shock level based on your CYA level isn't really necessary. That level of chlorine will do the job. It is still several days away from the weekend. If you are consistent with keeping your chlorine level up and run the filter 24/7, there is a very good chance that your pool will be clear for the weekend. Personally, I wouldn't want to swim with chlorine at shock level but it actually won't hurt you. Not good for swimsuits though. I wouldn't want to swim in water with algae in it, however.
