When you give yourself a range of upto 15 seats in an exit poll prediction, you can say later that you were bang on, whatever the outcome. The India Today-Axis exit poll gave the BJP 99-113 seats, and Congress 68-82 in Gujarat, so through the evening prime time the channel kept saying, "we got Gujarat right." Republic TV-C Voter had predicted 108, and as of noon seemed to be on track, but thereafter they ended up off the mark. The widest off the mark this time was Today's Chanakya's 135 +/- 11 for the BJP in Gujarat. News Nation's 124-128 for the BJP, The Times Now-VMR Exit poll which predicted 115 seats for the BJP and 64 for the Congress, and the ABP-CSDS survey by ABP News which predicted 117 seats for the BJP all ended up being off the mark. Moral of the story: better to predict a wide range of seats.
