Add speed as new metric/kpi

Incorporate Speed as a Target KPI: Adding speed as a performance KPI would provide valuable insights since it directly influences other metrics like edge angle and G-force. For instance:
• Higher edge angles often require higher speeds to maintain balance and control.
• Generating higher G-forces also necessitates increased speed for tighter, more dynamic turns.
Including this metric would help skiers better understand how speed integrates with other performance factors.
• Higher speed impacts balance on steeper slopes.
