User blog comment:ClariS/FEEDBACK! Cost Efficiency/@comment-5009341-20130106231200

i think u should use average gold cost of every stat,

rather than the cost of the cheapest item u can get it from,

since the more expensive items are more costefficient,

(basicly how riot calculates values; maybe they deleted ur goldvalues, cause they didnt matchup

e.g.:

Attack Damage:

10 ad -> 415g   (41.5g for eachj ad)

25 ad -> 925g   (37g for each ad)

45 ad -> 1550g (34.4g for each ad)

average 1 ad is 36.125g worth ((415+925+1550)/(10+25+45))
