Is it true that price for % potential equip in KMS is much cheaper than GMS ?

Sorry if this issue seems to be a bit old , but I've just read this topic on Basil :

http://www.basilmarket.com/forum/1706323...CHEAP.html

I navered(korean google) price for unique potential on Naver(most popular Korean search engine like google)
and the price for 15% stat is only around 250m.

in KMS miracle cube is 1200nx and package is 6 cubes for 6000nx(all nx items have pretty much the same price as in gms, only difference is they dont expire in KMS)
1000nx = 1000won
1000won = 0.86USD

ATK10 WG is 100m~150m(though this is very dependent on each servers, there are 32 servers in kms currently)
ATK 8 is 35m~40m

In, KMS it usually takes 20 cubes to make EPIK from RARE, and 30+ cubes to make UNIQUE from EPIK in KMS(i asked peaple in kms, some lucky pple only took 10 cubes from rare to unique tho)

so it normally takes 50+ cubes to make UNIQUE from RARE

-I also searched some more prices and this came out
10% stat(altogether) = 180m~200m
15% stat(altogether) = 250m~350m
20%+ stat(altogether) = 1b+


also have a look at this BM

he has 2727(868+1859) DEX (watch in 720HD larger screen if you want to see this)
which is 214% Dex from bas dex

Potential Equips came out on 21st May 2010 in KMS

Isn't it Kinda weird? or is it that the GMS is highly infalted?

I just wanna ask , especially from someone who has played both KMS and GMS , if it's really true ? And if it is , is it really because of the cubing rate of KMS ?
I have an argument with my friend about this issue , but he didn't seem to find the url above persuasive , so I want to have some more info regarding this topic . Sorry for the inconvenient

P/s : Btw , I think it's still big bang patch in the Korean link , as it was wrote on Sep 4th 2010 . KMS shouldn't have updated Chaos at that time .
And I just want to know generally about this piece of info if the price is cheaper or somehow the rate seems better or stuffs , no specific at all
