CYA target level

Just curious will the FC always fall quickly to the target level? Let’s say for example my SWG pool my current CYA is 80 (target level 6). If I raise my FC to 10 using LC and my daily FC demand is 3 and my SWG is set to produce 3 FC will my FC still fall to 6 as its trying to get to the target level? Always wondered this.

No. As long as your SWG is generating as much FC as is being lost per day, your FC will remain at 10. It's up to you to adjust your SWG run times to achieve and hold the target level.
