Formula change on expert delivery ?

Not sure if anyone noticed but ... all items over i200 are proportionally worth -less- GC seals when turned in.

Up until i200 the valu is 5.75 times ilvl, rounded up to the next whole number -- so an i100 item is worth 575 seals, an i180 is worth 1035, etc.

But once you get past that i200 mark the converfsion rate dropped -- an i215 item for instance is worth 1180 seals (should be 1237), and an i230 item is worth only 1230 seals (should be 1323) ... just strange.

I can't find any documentation to back up this deviation/change tho ...
