Restart sensor and just wait?

I have been using Dexcom G6 for about 2 months, and have restarted 1 sensor which was successful and lasted total of 20 days. Yay! I’m restarting another one today. The numbers can be kinda funky at the beginning of the restart, as you guys know. Do you just let them float a while before calibrating? Or how soon do you start calibrating?
