Timer starts from wrong value on void Start or Awake?

So I have a strange question. I am absolute beginner and I may be misunderstandign things but this is timer code I use:

public class BasicTimer : MonoBehaviour
{
    public float timeRemaining = 10;
    public bool timerIsRunning = false;

    void Start()
    {
        // Starts the timer automatically
        timerIsRunning = true;
    }
    void Update()
    {
        if (timerIsRunning)
        {
            if (timeRemaining > 0)
            {
                timeRemaining -= Time.unscaledDeltaTime;
                Debug.Log(timeRemaining);
            }
            else
            {
                Debug.Log("Time has run out!");
                timeRemaining = 0;
                timerIsRunning = false;
            }
        }
    }
}

All seems fine and dandy… however when I click play in editor, the value doesn’t start at 10 but 4 less (yes, I have checked inspector). If I however make it so player has to click left mouse button in the update, it starts at correct value.

The reason I use “unscaledDeltaTime” is because my game is sped up slightly in project settings to 1.3 Time Scale (it is required).

Any reason why timer is off by 4 seconds on Start() and Awake()?

Is it possible that the time gap is due to the time it takes to start Unity/enter PlayMode? The first frame might be taking extra long due to loading time.
