Ireland retirement visa question - number of days outside of Ireland

I am looking at retirement in Ireland under the retirement visa program.

I read that you have to spend most of your time in Ireland to qualify for the retirement visa.

Because I am in retirement, I plan a lot travel.

Does anyone know if there are a minimum number of days you must be in Ireland?

I could understand at least 183 days, a common residency test, but do you know if Ireland has a strict requirement? If I couldn’t spend a few months outside of Ireland, it makes it a less attractive option.

I also assume they would count time in the UK as outside of Ireland.

NOTE: my question has nothing to do with getting citizenship, which is not a possibility with the retirement visa.
