Thanks! Well, better than the other data indeed, but looks strange. Before paragon 1000, having the same levels in season and non-season would result in not more than 100 paragon more (as a rough rule of thumb). According to this, if I take the example of Vajet (who's quite high in both season and non-season paragon) he'd jump from p1339+p1358 to p1662 after the season, more than 300 levels gain. It might just be because of the crazy amount post-p1000 XP needed per paragon level... who knows.
I'll use this data for now, until someone disproves it - but it would really be great if some p1000+ guys could just post how much they need for the next level, so we can "validate" the table. There are enough out there ;-)
No it's because before paragon 800 the xp per level needed was irrational. You always had different xp per level jumps. After 800 the xp per level is rational again and you need exactly 122.400.000 XP per level. I can confirm that both charts are correct and still up to date, since I am a pretty high paragon player aswell.
If the spreadsheet is correct for lower paragons, there are XP patterns all the way down. Even the 122,400,000 pattern extends down to p750.
>p750 = add 122,400,000 to previous lvl's xp req
p701-750 = add 102,000,000 to previous lvl's xp req
p651-700 = add 81,600,000 to previous lvl's xp req
p2-60 = add 1,440,000 to previous lvl's xp req
