For the same exponent, double check & frist time LL take the same amount of time (on the same kind of CPU, natch). They're basically the same computation sequence (the random shift count not withstanding).

However, at any given point in time, the exponents given out for first time testing will be much bigger than the ones handed out for doublecheck. Does that answer your question?
