Why are CSK above RR on IPL 2026 points table despite same wins, points and NRR?

CSK are placed fifth on the IPL 2026 points table, ahead of sixth-placed RR, despite both teams having six wins, 12 points and an identical NRR of 0.027, as per the IPL website. CSK are ahead because their NRR is marginally higher beyond three decimals. If that too was identical, RR would've been ahead on the wickets-per-fair-ball criterion this season.
