In the past 12 months, India have lost just one T20I (against Sri Lanka in the recent ICC WT20 final in Bangladesh), while Sri Lanka have lost four matches. The 2013-2014 results are weighted at 100 per cent whereas, the results in 2011-2012 and 2012-2013 are now weighted at 50 per cent. Therefore, Sri Lanka's strong performances in those two earlier years now count for less.
