Those numbers look reasonable. You can’t compare advertised salries with actuals. Did you actually get an offer $110-115? Most companies aren’t going to list their salary they’re actually willing to pay, they know that most people are going to negotiate.
You don’t say if the 110-115 numbers you’re talking about are from Irvine listings.
Even if they are, being able to negotiate an extra 10% doesn’t seem far fetched. You also have to remember that the numbers are averages. The best and brightest don’t generally look for a job through standard job listings, they’re recruited. That represents the high end of the salaries. So the low end from standard job postings doesn’t really seem too far off.
