Yield boost

So today I staked 4.99919 CAKE on a CAKE pool. And I am getting 82.43% APR/APY. But it also says yield boost. And what is that exactly??? ‘Cause I have 2 theories

Theory 1:
When I staked my cake for 52 weeks. When I restake it the APR/APY boosts x20.95

Theory 2:
Over the course of 52 weeks. My APR/APY will increase 20.95X

Please tell me if I’m correct or just straight up wrong.
