Nothing new for those who’ve already done the math, but there are always new candidates coming up.

Frankly I find all these "talking head" tutorials a waste of time. They take 20 minutes to talk about something I could read in 5 minutes. I guess they could be useful to some. This one in particular seems to be selling their services. Which is OK. It takes time and effort to make one of these. They should hope to be compensated for that work.
The problem to me is the conclusion always seems to be "it depends."
The previously cited
https://www.bogleheads.org/wiki/Roth_IRA is a pretty good source. But it is also long and complicated. Probably because tax laws are long and complicated, and pretty much out of our control! Has anybody made a better tutorial? Does ER have one?
I personally think making a good Roth conversion tutorial is impossible! Too many variables. Too much guessing what the future might hold.
I do think everybody should have a Roth account. Even a small one. Just to start the 5 year clock.
I'm currently in the 12% tax bracket, and expect to stay that way. So for now I'm converting up to the top of that bracket. Worse case I break even, unless income tax rates go down, which seems unlikely, but possible.
Essentially by making Roth conversions you are guessing which way tax rates will go. You are also guessing how much of your "income" will be taxed.
Assuming tax rates, and rules, stay the same, you have nothing to loose by converting at your current tax rate.
My next car, or roof, or other thing, will likely be paid for by my Roth accounts.
