Is there an estimate of how long Lucien lived in the Spring Court // At what age did he leave Autumn?

I understand that we don't even know his age with precision, but I've seen people make close predictions about some characters using the IC ages and the war as reference (for example, the plot holes regarding age in the Mor X Eris situation).

Somehow, I've never seen people discuss for how long Lucien lived in Spring and it impacts some aspects. Did he spend most of his life in Autumn? Did he only spend his youth in Autumn? Is it about equal?

It gives us more information about his identify. About his relationship to his brothers and mother, his relationship to Tamlin and his role and importance in Spring, his connection to everything that happened with Jesminda and how it impacts his mating bond...

Ofc, canonically, the minimum possible would be about 50-51 years, because that's the time of the curse and book events. Although we definitely know it's longer than that because Lucien had to settle, get a name for himself in Spring, and get close to Tamlin and all.

Does anyone have more knowledge or a solid guess at this?
