you don't need to "overfeed" arcanas when the card's level is low. you can either:

a) use the wiki's stat info to calculate exactly how many arcana you need to feed and just feed that exact amount or a little less

b) stop feeding arcana when you are ~1000-2000 stats away from the max possible stat and just feed the rest once the card reaches max level.

the Arcana+ are not easy to obtain. you get 1-2 per event on average.. but don't consider these special by any means--they are simply the equivalent of 10 regular arcana, or 1800 medals--- just 18 Rs or 1 SR.
