What is the benefit of doing the FoY a second time?

(v19.5 ... as things keep changing)
After having turned a centenarian for the second time, I was wondering if there is any reason to do the fountain of youth again? Currently there is no debuff and my character still seems to have the stat gains from doing it the first time.
Has anybody tried and tested?

yep I did it a second time it gave me a 5% buff added to the original one

Some say that it goes +5% third time and then that's it. No more buff stacking just 20%.

worth it for the buff , after that who knows why

I already did the 2nd time FoY and got the stats bonus.

You get bhffs the first 5 times you do it apparenttly. After that the only benefit is to stoo the old age debuff which you should still get, it just doesnt show it on the bottom right now.
