Re: England V SA
The highest total in T20 cricket is Lanka’s 260/6 vs Kenya but even in that game Lanka reached 50 in 5.5, 100 in 9.5, 150 in 12.4, 200 in 16.2 & 250 in 19.2 overs
The highest total vs a test team is Australia’s 248/6 vs England. Aus reached 50 in 5.2, 100 in 9.2, 150 in 13.3 & 200 in 16.1 overs
Records | Twenty20 Internationals | Team records | Highest innings totals | ESPN Cricinfo
So this is the fastest fifty (2.5 overs) & joint fastest hundred (7.3 overs, also WI vs SA) in all T20 cricket
