No Serious Business - IEM Edition

@Rikudou_Goku summoning you here since this is a pararel but off-topic to that thread.

I’m about to do a ranking list for personal use. In you opinion, if you had to quantify price to value ratio, what equation would you use? I’m interested in your insight.

Price / Total rating (let’s say 1-10 or 1-100) ?
