I rebirthed in Nov of 2011:

   Rebirthed on Sun Nov 06 02:54:45 2011 with totals of 675M
   Rebirth experience left 102565.

I had 675,102,565 exp when I rebirthed

Over Batmud's 29th Anniversary weekend I was able to make it back 675M exp. 

   Total of 675,540,303 experience spent on character.

I now have more experience that I have ever had on Batmud. 

It took me approximately 6yrs 5 months to regain my total experience. 

Wow, that took a long time.

I made about 255M exp or 38% of my total experience since January 1, 2018.

It was mostly a lack of motivation and losing interest. I didn't play for long
stretches of time. 

Something that I noticed was that there was a noticeable increase in my
character's power and ability around the 400M mark. Whereas I might have
struggled here or there or lost motivation due to stagnation, I finally "felt"
like I was able to play the game effectively at that experience. I'm sure
there's a lot more to it than just total experience, but that's the most
noticeable effect. 

My 'show reincs' doesn't show when I reincarnated to Liberator (because I've
used the various "free" reincarnations that have been made available over the
past couple years), but the last reincarnation that is listed is Jan 18, 2016
with a total experience of 279M. Which means that it took me almost two years
as a Liberator to get from 279M to 420M (+141M).
