No, that is from scientific research papers. See my earlier post already on the same question.
My personal experience here in Finland is limited to keeping batteries from freezing.

And there is very little capacity below 3v.
I cycle between 49v and 56v.

IF you are cycling 100 to zero.
I think if you are regularly getting that low, you need a bigger battery.
Using your example, if you cycle down to 50% and back to 100% for two consecutive days, THAT is one cycle.
So, 7600 days. To 80% SOH.

Whatever you did, that's what you planned.
That's certainly true with lead acid, it might be even be higher but only time will tell how things work out for LFP.
I tinkered with lots of off grid systems over the years. T105, L16's, 2V Rolls/Surrette's and HUP's, 2V AGM Telecom's and the list goes on. I honestly don't think I ever saw a lead acid battery bank die from cycles.

Oh man, yeah I worked at a battery store when I was a teenager and the only batteries you'd legitimately believe died by cycles were daily driven car starting batteries. When someone would bring in a 10-15 year old car with its original battery in it it's like "you did good little guy, you did real good". None of the aftermarkets would ever last as long as that original either, I guess the car makers just have higher standards and know how to enforce them, they don't want to be replacing batteries under their manufacturers warranty.

If I can do it, you can do it.

Depending on the size of your battery. 10% can be quite a bit of capacity.
I can do a lot with 20 or 30 kwh.
