These tend to be very unpredictable. Small ones can explode up into a huge crack very quickly, or may be easily repaired -- hard to tell.
I just had a total replacement a month or so ago -- and two weeks later, another hit in the same place, but smaller this time. Safelite came out and did a machine repair. Stopped it at about the 1/2 point and it's way over on the passenger side. Frustrating but acceptable. Good luck with it.
Also check your state's insurance regs. In FL we get windshield replacement and repair with no deductible. One of the few sensible provisions in FL insurance law...
