The body was not in the desert, he took into account the weather, Sant Ana winds, moisture, animals, mummification etc. They discussed literature about bodies in Arizona and mummification at length.
Everything Dusek tried to gain failed. I watched a video of the tetimony again and I am convinced, I suggest you listen to it or read the transcript and reach your own conclusion.

I have no problem that their calculations are correct from the time the first fly arrived. My questions are the assumption that the fly's would arrive within a few hours of death.

Given that the desert doesn't offer an attractive set of circumstances for flies to find places to grow I doubt nature would have them waste much time there. I am willing to bet that the scientists in this area haven't done much studies on the desert and have merely extrapolated their work from other areas with an untested assumption that flies would arrive in a short period of time.

After finding a second case where all of the evidence contradicts the fly guys and the same case was in the desert I wonder how accurate their assumption is that the flies arrive right away.

Common sense says nature wouldn't waste the time sending flies into the desert and the two cases with two similar time problems indicates a time delay.
