Cost per VESTs is still higher but the supply of steem have more than doubled since then so the cost per vest should actually be a lot more higher.
What? You're the one explaining (correctly) that rapidly inflating the number of STEEM doesn't actually do anything. VESTS is not particularly an inflationary unit. The number of VESTS has only increased slightly since July. What the price of VESTS having increased (slightly) tells us is that the market cap has increased (slightly).
I think we'd probably all be better off seeing prices quoted and charts made on the basis of VESTS.
