I disagree. Things have changed. .
Looking at your first post your goal was for $16K in monthly spend. You're now at $25K so things have changed. I don't fault you for that, things get more expensive as I'll discuss below.
Many here have focused on reducing spending. I'm not going to do that because when I retired at 51 I told myself I'd only do it if my lifestyle would say the same. I was not going to compromise on they way my wife and I liked to live in order to FIRE. Many here do but not I. My first post on here was similar to yours with slightly lower numbers. I too was chastised for spending levels and told I should cut everything. It's what many people here do. Take that with a grain of salt and decide your own lifestyle needs/wants.
IMO (and experience), your expenses will go up as your kids get older. Their hobbies/activities get more expensive not cheeper just like yours have. Cars, insurance, dating, weddings, family trips, etc. all get more expensive. Not to mention grandkids and then everything gets even more expensive.
My kids are both out of college and on their own in different states. We visit each at least once a year and fly them here when they want to visit as well. We still go on family vacations that I pay for because I feel its important. When they are married and have kids I'm sure we will be going their often. For vacations I'll probably take the whole family, because I feel its important to share that time.
The major flaw I see in your planing is modeling to 87. In todays world that is way too young to plan for. At that point your wife will only be 77. Whats her plan from there?
Also make sure your taxes are conservatively covered in your budget. Most of your money is in taxable accounts. I'm not convinced that capital gains will stay at 15%. I'd plan for higher and be happy if they don't.
My FIRE plan was to plan for the worst for both longevity and spending. Worse case scenario is that my kids inherit more than I intend.
