Since for whatever reason (despite voicing my discontent at the time) this group buy used "chips per bitcoin" instead of a fixed price of "bitcoins per chip" (chips aren't divisible, bitcoins are...) as the dividing metric, I calculate that the original cost was 0.08016525 BTC per chip. This included escrow fees at 1.5% to JohnK, chip shipping costs from Avalon, ragin's 1%, but NOT redistribution shipping from ragin to buyers as that was to be paid individually to ragin at a later date.
782.1 BTC * 1.025 (1 percent for ragingazn628 and 1.5 percent for johnk ) = 801.6525 for one order
801.6525 / 10000 = 0.08016525 per chip
Ragin is (rightfully) forfeiting his escrow fee of 1%
John K's escrow fee is therefore 782.1 * 0.015 = 11.7315 BTC
Ragin's fee (returned to the group is) 782.1 * 0.01 = 7.821 BTC
Refund available is therefore 782.1 (chips plus shipping) + 7.821 (Ragin's share) = 789.921 BTC available for refund
Math check: 801.6525 (collected) - 11.7315 (JohnK's fee) = 789.921 (check)
(no sample chips accounted for in the calculation; at time of purchase this wasn't indicated as part of the deal...)
Refund issued per chip is thusly 789.921 / 10000 = 0.0789921 BTC per chip
This should be issued to all present documented chip holders in the group. Cost from after the fact sales amongst group members should not be accounted for as the sale constitutes a transfer of risk, and would make the refund entirely too complicated to process.
Your math checks out. Please double check I got it right on the chip count sheet.
Also, I fully agree that second party sales prices will not and should not be considered.
Well not exactly, that only works in a perfect world
we have
790.51250333782.1 from the refund.
7.821 set aside that was to be raging's fee.
0.59150333 remaining in this group buy's btc address.
there are a lot of addresses in the group buy escrow address and john k. can explain them
John. K's amount was already taken out, so regardless of what it "should be" it is 790.51250333 or 0.07905125033 per share unless some of those mystery addresses are under john. k's control, in which case it is greater.
Of course, I think Raging should pay for those chips... in which case the share per person would be 0.07930502641 after subtracting 32 shares from raging.
