Precisely what I said! To think that a 256 is only "decent" is just not right. Avg rads step 1 and 2 is much lower than that, and given the down turn in rads competitiveness, you can get into good programs with much less than that these days. And given that many good programs don't even start looking at apps until Dean's letters are out, it's not an issue to apply now.
As aPD said he doesn't care if someone applies on 9/15 or 9/30. As long as it's reasonable most apps are looked at. Also many programs review by step scores, so given the high step score of the OP, he is likely to get a look even if he did not submit right away.
