I am planning to retire in early 2022 at age 54. I will be 55 in late 2022, so plan on using rule of 55 to access company 401k.
Total portfolio is about $1.33m. Plan to save another 35k before retiring. I'm not especially looking to reallocate assets or choose different funds, although I'm open to suggestions. I've more or less settled on target date funds for the simplicity. We will aim to keep about 60% equity, switching funds as needed. We may start gradually decreasing equity to 40% equity or so once we get closer to age 70.
Our current expenses are about $52k/yr. I'm estimating $55k/yr in retirement to allow for some extra unplanned medical expenses each year. I expect to use a marketplace plan with tax subsidy for health insurance until Medicare is available.
Once SS and my small pension kick in, I think most of our expenses will be covered by those. Our plan is to take social security when I am 67/spouse 68.
I've run our plan through several of the online calculators (firecalc, etc) and those indicate a high success rate (90%+). We do have some spending flexibility to temporarily reduce spending by 3-4k/yr if stocks have a big pullback. Worst case, we are both open to a part time job or whatever, but I'd rather not go in having that be a requirement.

Questions:
1. Does this seem like a sound plan? Are we on track for early retirement in 2022?
2. What am I not considering?
