Sounds reasonable to me.
I don't think I remember seeing an unfinished basement floor without cracks. I have cracks in mine. But I don't have any water intrusion issues. I guess the builders anticipated the floor possibly cracking, and put down the proper drainage, etc so it would not be a problem.
Somebody on this forum once posted a great quote that I will never forget: "there are three sure things with concrete; its heavy, its going to crack, and nobody is going to steal it from you".
Cracks on a basement wall are a different issue, since whatever minimum code is for extrerior protection of a foundation wall, its not sufficient. But again, cracks are anticipated, and measures are taken to mitigate the consequences. (even if it can be argued that the measures taken are inadequate.)
Sorry, I can not give a quantified anawer on what is excessive cracking a new basement floor, but if you don't have any water intrusion issues, likely its not a reason to worry.
