The Eidolon's evolution points mentioned on the table aren't specific as to whether they are cumulative (26 total evolution points at level 20) or non-cumulative (gaining 26 new evolution points at level 20). Either interpretation seems problematic, as follows:
1)It is not possible to save evolution points from one level to the next, and no level gets you more than 2 "new" evolution points under the cumulative interpretation (except at 1st level). So, under the cumulative interpretation, it's not possible to have any evolutions requiring 3 or more points.
2) On the other hand, using the non-cumulative interpretation, one can access virtually all of the evolutions available - it's just a question of which evolutions one wants first. While I haven't had a chance to actually build an eidolon yet, I suspect that a 20th-level eidolon would steamroll any animal companion or mount and have a good chance against a lot of melee-oriented player characters.
So, which is it? Or is there another way to read the table?
