Circular score bar - a better way?

Hi everyone,

I'm working on my first mobile game with Unity and these days I'm focusing on a circular score system to be shown on the game over menu. This is the solution that I've found:

 public class LevelRing : MonoBehaviour
 {
     [Header("Score Variables")]
     // Score stored as a scriptable object
     public IntVariable CurrentScore;
 
     [Header("Elements")]
     // The image used for the filling
     [SerializeField] private Image m_RingImage;
     // Text Showing the level
     [SerializeField] private TextMeshProUGUI m_LevelText;

     // 5 points per level
     private float m_MaxValue = 5.0f; 
     private float m_MinValue= 0.0f;
 
     private float m_CurrentValue = 0.0f;
     private int m_LevelToShow = 1;
     private int cirlcesDone;
 
     private void Start()
     {
         m_CurrentValue = 0.0f;
         m_LevelToShow = 1;
         cirlcesDone = 0;
     }
 
 
     private void Update()
     {
         UpdateFillRing();
     }
 
     private void UpdateFillRing()
     {
         int numberCompleteCircle = CurrentScore.value / m_MaxValue;
         float remainingPercentage = (CurrentScore.value % m_MaxValue) / m_MaxValue;
 
         if (cirlcesDone < numberCompleteCircle)
         {
             m_CurrentValue = Mathf.Clamp(m_CurrentValue, m_MinValue, m_MaxValue);
 
             if (m_CurrentValue >= m_MaxValue)
             {
                 m_CurrentValue = 0.0f;
                 m_LevelToShow += 1;
                 m_LevelText.text = m_LevelToShow.ToString();
                 cirlcesDone += 1;
             }
 
             float fillPercentage = m_CurrentValue / m_MaxValue;
             m_RingImage.fillAmount = fillPercentage;
 
             m_CurrentValue += Time.deltaTime * 2;
         }
         else
         {
             if (remainingPercentage > 0)
             {
                 if (m_RingImage.fillAmount < remainingPercentage)
                 {
                     m_CurrentValue = Mathf.Clamp(m_CurrentValue, m_MinValue, m_MaxValue);
 
                     float fillPercentage = m_CurrentValue / m_MaxValue;
                     m_RingImage.fillAmount = fillPercentage;
 
                     float t = fillPercentage / remainingPercentage;
 
                     m_CurrentValue += Mathf.Lerp(Time.deltaTime * 2, Time.deltaTime/4, t);
 
                 }
             }
         }
 
     }
 

The code works but I don't feel that is the right approach to it! What do you guys think?

Thanks for the help in advance.
