It looks like you got what you needed, but I wanted to add a few things. First, if you're 50 something catastrophic would have to happen (and it might) for Social Security to not be there for you. To be honest, I'd have a lot more faith in Social Security than any state's pension. I think it would be a good idea to calculate how much you'll get from Social Security and, as SeattleCPA said just multiply it by 76% (I use 70%, but whatever) to get a pessimistic view of what you'll get.
Second, I recommend looking at the Investment order thread.
https://forum.mrmoneymustache.com/investor-alley/investment-order/Third, I wans to reiterate what reeshau said. Write up a case study. It's entirely possible that you could shave 6 months, 1 year, or even 5 years off your time to retirement depending on how open you are to trying to cut expenses and how much fat there is in your budget.
When do you qualify for PERS? It's entirely possible that you could save 1/3 of your post-tax income for the next 10 years to fund the 5 years from 60-65 (if that's when you get PERS). If PERS covers your spending then SS, which is likely to be significant, could give you a bunch of fun money.
Congrats! It sounds like you're in good shape, but you might be able to still get to an early retirement - possibly while you're still in your 50s!
