I find it good to remember that genes are like re-used variables that do 100s of things in a giant 1mil lines of code file. Just cuz they identified one gene doesn't mean that it doesn't require other activations as well. Or that expressing that one gene will have that much of an effect. So sure, you could have an idea of the upper limit but definitely not the whole story. Circulating levels of GH/Insulin/IGF and other hormone like chemicals also play a huge factor in longevity as well. https://pubmed.ncbi.nlm.nih.gov/22396862/ https://pubmed.ncbi.nlm.nih.gov/22396862/
