I don't think any points or run rates are being carried forward. Not 100% sure, only 80%.
But this tournament format is starting to bug me. There are 4 games in the next 2 nights - and only 1 of them matters: Pakistan v Netherlands. The other 3 do nothing at all as there is nothing to play for. All the spots are pre-determined. So 3 of the 12 prelim games will have been pointless. Good for ticket holders for the Super Eight games I suppose who know where their team will be playing, but that's the only advantage I can think of, and since those games are all double headers anyway it probably doesn't matter much.
This predetermining of Super 8 spots could have been a negative deterrent too to good cricket too. Imagine if Australia had scraped past Sri Lanka last night. They then then be in the position of having to rely on Sri Lanka beating the West Indies quite well to get through, or Sri Lanka losing again. What's to stop both the SL and WI teams getting together and 'manufactuing' a result to make sure they both got through? Ie. matchfixing. Neither team would have had ANY incentive to play hard because they already knew what Super 8 group they will be in if they go through.
T20 may be an entertaining format, but I don't think much of the tournament setup.
