Some good news for the bulls (in a market sense)



602 samples now. Finally got a prize greater than 20g... too bad it's only the 50g prize. It does raise the fair price estimate of the [Mysterious Fortune Card] by a bit though.

Pay attention to how the error estimates shrink over time. More samples = less uncertainty!

The prices of [Mysterious Fortune Card] have come down a bit on my server, to somewhere between 30g and 40g. Having collected this much data, I'm pretty certain at this point that the cards are not worth that much. If I were to win the 5000g card on the next draw, it will only bring up the fair price to something around 9.7g. I would have to win the 5000g prize three times in a row to make the fair price about 30g. There's no way that is happening.

  1. While you're probably right in that winning the 5k one three times now is unlikely, it has (sortof) happened before.

    I had a guy buy 5 of these off me and got 2 x 5000g cards.

    What I'm trying to say here though is that while 600 cards is a large sample, it's not, at all, large enough to actually be as accurate as you think :).

    I love the effort though and I really do hope you'll keep this up. Seeing these numbers with a 3-5000 card sample will probably start to make the data more accurate.
