H.L. Mencken observed: “For every complex problem, there is a solution that is simple, neat and wrong.”
IMO that applies to all these general rules on AA. Subtracting age from some number, etc. The "right" AA depends strongly on the value of your assets compared to the rate at which you need to draw from them. (As @Car-guy points out.) It also depends on your attitude towards risk. "Do you want to eat well or do you want to sleep well?" Finally, it depends on your age and your objectives for heirs and other beneficiaries of your estate.
In our case, we have handily won the game, so we could certainly go to 100% conservative assets. We are 70YO, so the "rules of thumb" might tell us to go 50% or less in equities. But we are just redoing our allocation to go 75%. Why? Well, TBH, the game is kind of fun. But also our estate plan has two testamentary trusts for our sons, so we are really investing that money for them. It also has charitable components, so we are investing for those beneficiaries as well.
To beat the horse a little more, consider two 70YO widows whose parents led long lives into their 90s. The conventional wisdom and the far-too-simple age formulas would advise both of them to have the same AA. Now I tell you that one has $200K of assets and one has $10M. Does the same AA suit both? Of course not.
So ... there really is no answer to your question except the one you come up with for yourself. No one else's experience applies. As @Dtail suggests, play with the various calculators to see possible scenarios, understanding that they are simply projecting history into the future and cannot actually predict the future. Then make your choice.
