Yikes!  My planning is much more basic than the work you've done in your referenced thread.  Yet the way I sold in prior spikes (small frequent slices as the bull markets were in full swing and soon after the ATHs) was similar enough (though unstructured) to your spreadsheet suggestions.  I do not plan in such detail for a few reasons:

1)  at this point in my retired life I tire of spreadsheets
2)  things change so fast that I will make decisions, sometimes, on the fly
3)  I have never had enough BTC to attain one of your FU status amounts, but that's fine with me as my wife and I are retired OK, you may remember me re 1% - 2% of net...
4)  my sales-in-slices strategy worked well in 2017 and (especially) 2021
5)  I might not have the discipline to follow a plan...

I certainly concede that my somewhat relative success has been in at least part due to luck.  But, as I considered in the past with my own views of probabilities of price movements both uppity and downnity and our financial situation and rather plebian knowledge of Bitcoinistan, I was just fine with the gains I made.  Which have not been game-changers, but that's OK.  Especially 2021...

My game plan is likely to be "rather 2021-ish."  Sell off small slices every once in a while, maybe once or twice a week, once we reach some $80k.  In 2021, I started selling at $30k, and sold off slices throughout the double spike.  I then started buying again at some $40k - $45K (too soon, oops).  My last purchase was just this Monday, I haven't made up my mind when I'll buy again.  My buying more-or-less conforms to the spirit of DCA even if sloppier, but, hey it works without overly taxing my brain.
