LindeX USD amounts differ for same exchange rate

Hey there, why is it that when I sell Linden Dollars I get different amounts of USD? See below for a snapshot of my transaction history. You can see I sold L$10k three times got US$35.72, US$35.77 and US$37.74.

Is that guy from Superman III skimming fractions of a penny off my transactions?

I'm guessing that what we're seeing is the result of some rounding, either in the exchange rate or in the fees, but I've asked Lawrence to confirm.

As have been previously discussed, where LindeX does rounding it does so in favor of LL. Since large transactions can be matched with many smaller transactions this often results in slightly different grand totals due to rounding.

I've had it on my todo list since LindeX launched to go back through the rounding and adjust it to always round towards what makes the math be off no more than half a penny for the whole transaction. I'm not sure when this will be addressed, but I'd like to get to it before the holidays if possible.

Cheers,
Lawrence
