Frequently asked questions
What is Nayef's damsire IV?
Nayef's damsire impact value (IV) is 1.05. It is the win rate of runners whose dam is by Nayef (11.1% from 5,417 runs) divided by the win rate of every runner in our breeding database (10.6%). So 1.05 means those runners have won 1.05 times as often as the average runner, 5% more often; 1.00 would be exactly average and anything below 1.00 less often than average.
