Coroutine, Timer Local vs Class variable difference

Hello, I'm writing a shooting script, and i'm using Coroutine to delay my shots.

Here's the issue, i realize using delta time on a Class variable is inaccurate compared to using a Local variable. For some reason, the class variable timer is causing the gun to shoot faster.

Can some please explain to me why this is happening?

 protected IEnumerator TimerCountdown()
 {
     float counter = timeBetweenShots;
     while(counter > 0f)
     {
         counter -= Time.deltaTime;
         yield return null;
     }
     canShoot = true;
 }

     {

     }
 }
