Scenario 1:
40) SRH wins vs RR
41) DC wins vs KKR
42) MI wins vs PBKS
43) RCB wins vs RR
44) SRH wins vs CSK
45) PBKS wins vs KKR
46) DC wins vs MI
47) CSK wins vs RR
48) RCB wins vs PBKS
49) SRH wins vs KKR
50) DC vs CSK : doesn't matter
51) RR wins vs MI
52) SRH wins vs RCB
53) CSK wins vs PBKS
54) KKR wins vs RR
55) SRH wins vs MI
56) RCB vs DC : doesn't matter
scenario 2:
reverse results in match 42, 45, 51 & 54 (all 4 matches)
in both scenarios
CSK, DC will finish in top 2, RCB at 3
SRH will have 12 points, while PBKS, KKR, MI & RR will finish with 10 points.
very unlikely, but mathematically possible.
