Sorry for bringing up a somewhat vacuous question. I've applied for PhD study in particle theory at 9 US graduate schools. 6 of them are among the most prestigious schools, and the remaining 3 schools are Chicago, Rutgers, and Stony Brook. Half of these schools have given out their first wave of offers, starting from one week ago. But I have heard nothing yet, and I'm starting to get seriously worried as it is approaching mid February. On the up side, I come from a top UK university and have high grades and high GRE scores. On the down side, my research experience is weak, and my recommenders all work in areas of physics other than HEP, due to the fact that my department only has a small HEP group. I'm wondering what percent of the offers are typically given out in the first wave? Shall I interpret the lack of responses so far as an indication that I need to adjust my expectations and focus on some plan B instead? Thank you for you opinions.
