In January no one gave Indian cricket team any chance in the World Cup. After yet another disastrous tour overseas, at best people expected a quarter final berth. And that too because the format is such that it is really difficult to eliminate top teams (unless you are England). After the WC 2007 debacle, ICC ensured India is not knocked out of tournaments early and moved to just a two group format where one could somehow managed the next stage.
Same stands for Indian economy. Till Jan, most forecasts were hovering around 6-6.5% growth. And then suddenly came the magic wand from CSO which revised the base year and numbers in a big way. The fortunes turned around suddenly and the forecasts moved to 7.5% – 8% range. From a sour spot of low growth high inflation, we overnight moved to sweet spot of high growth-low inflation (as CSO revised the inflation numbers lower as well based on new series) numbers.
