Better look ahead (try not looking on your pair while solving, instead look around the cube. Blind pair insertion practise is good)
Your turns per second when you are turning is significantly faster than mine, but I average around 16-18 seconds now, because I turn slow enough to look ahead. You spend too much time between solving pairs.
