Evolution Surge and the point limit

[standaloneghost]

Question is as thus... I have +4 str from 2 picks of enhancement, costing me a total of 4 evolution points. If I evolution surge, can I pick up the large size evolution? It says it double the requirements of stat enhancement evolutions, but does that necessarily apply since im picking up large for a limited time via a spell?

you can use evolution sure to become large. Basically what
"The ability increase evolution costs twice as much (4 evolution points) when adding to the Strength or Constitution scores of a Large or Huge eidolon."
means is that when you level and allocate evo points if you choose large evolution you have to pay twice as much for ability increases. If you become large (through enlarge person/ evolution surge) your ability increases don't suddenly cost more.
