I can't answer that, because DS's packet was reviewed right out the shoot and he was given his scholarship after meeting the board (CAVEAT: AF, which is different) However, I recall reading on these boards, kids receiving letters that they were not selected on XXX board and will be put up again for the next board. SO I AM
ASSUMING like the SA's you can keep upgrading.
I have to ask why you would submit now if you feel it is not at the strongest it could be? If he takes the SAT in Sept, his results will be available in Oct., that is still very early in the scholarship season.
With the economy the way it is, the services are seeing an increase in applications, thus the competition is getting more fierce. 2 yrs ago you saw almost everybody getting some form of a 4 yr scholarship, last yr, I saw for the 1st time kids getting scholarships for 2K, I didn't even know that those existed. At our DS's hs, 3 kids got the 4 yr scholarships, the irony was known of them were JROTC. The 7 JROTC students that applied, did not receive any. My point is it is about your childs application that will determine if they get it. I will say the JROTC kids were quite upset and disappointed.
Finally, a 30 is a good score, it is the equivalent of a 1300+. They take the best of the 2, so if the SAT overall is higher than the ACT, they will judge him on the SAT, and if the ACT equivalent is higher they use the ACT
Here's the equivalent link

In our sons case his ACT turned out to be higher than his SAT, only by 20 - 50 pts, but still it was 20 -50 pts. His ACT put him in the 1400+ out of 1600.
