We were bouncing around from 1 to 10 over the past two months. Ranked #1 for 3 days then fall out for a few days. This kept repeating until a week ago when we were ranked #1. I thought things finally stabilized after no changes for a week until I woke up this morning to see we had once again fallen out of the top. This is a long term client whose site is about 15 years old, 150 google reviews, loads extremely fast, around 600 pages indexed by google.
