Absolutely raise it to the maximum for your CYA which is 10ppm. Falling below minimum can cause great havoc on your pool. And plan to make sure it's at 10ppm every night before you begin the next day. You're going to loose about half of your chlorine every day, and want to remain at or above your minimum of 5 at day's end. As such 10ppm is necessary for a full day of swimming and sun.
If 10 ppm seems too high, you can do a partial drain to lower CYA to around 40ppm where you'll then need to make sure you raise it to 7ppm at night and never fall below 3ppm. Same ratio, but lower chlorine use/day. If you're in a very hot climate, 50ppm CYA might be appropriate for you.
Adjust the calculator's now column for CYA, you will see different values change in the pink chlorine section at the bottom. The numbers that show there after you enter different CYA values tell you what to put into the target column for dosing calculations.
