If one fails there than I'd just dispose of it and assume it doesn't roll correctly.* After that I'd go with rolling evidence for my top favorite dice. <br /><br />* Further Research: A paper confirming that dice failing the water method also show as unbalanced in rolling tests.

He had 10 d12s, and he got a player to roll each of them 112 times and record the results (not sure why that number, but that's the data he sent me), and then he separately tested them in salt water. I haven't seen him over the summer so I didn't get a chance to find out the results of his test.<br /><br />The stats method definitely took ages, and I only identified 1 biased d12. However, based on the power of the test, I couldn't say with certainty that any of the other 9 were unbiased (I did some power tests and I think upping the number of rolls to about 200 would have been enough, but I don't have the working in front of me).<br /><br />So what do you reckon? I don't know if a die that fails the water test would also fail the chi2 test. It seems to me that rolling is the gold standard, but you need to do so many rolls that it takes forever. Also if you've got multiple dice then you'll need to roll them even more to stop the 1 in 20 slipping through with 20 dice.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2170237526012357403.post-33264068432291135942017-08-29T23:36:29.998-04:002017-08-29T23:36:29.998-04:00I wish there was an upvote button for this comment...I wish there was an upvote button for this comment.

All th...I've done this test on dozens of D20s.<br /><br />All the opaques failed and all the clears passed! <br /><br />Only one exception: one clear die failed that had a relatively large bubble on the side that was lighter. It turns out, the bubbles matter. <br /><br />No need to bring salt water to the store. Just avoid the opaques and check the clears for bubbles. <br /><br />The shape isn't an edge case. I've seen dice pass this test with flying colors while being so deformed some faces were actually convex.<br /><br />I've read that opaques are cheaper because they rush the production on them, because no one can see the flaws on the inside like they would be able to with clears. <br /><br />Tell the world.

But if we're talking about not-huge factors of unbalance, then it's not clear to me that it really matters. You still have epistemological randomness if not metaphysical randomness. And partly since one presumably is using a variety of dice for a variety of purposes, it's epistemological randomness which I would think would be the most important thing. I know I'm not putting it very well. Does that make sense?<br /><br />That said, the water test is fascinating.Oakes Spaldinghttps://www.blogger.com/profile/08078500142758654392noreply@blogger.comtag:blogger.com,1999:blog-2170237526012357403.post-39740135391815921672017-08-29T13:49:24.207-04:002017-08-29T13:49:24.207-04:00Do it in the winter and say you'll de-ice thei...Do it in the winter and say you'll de-ice their walk at the same time. :-)Deltahttps://www.blogger.com/profile/00705402326320853684noreply@blogger.comtag:blogger.com,1999:blog-2170237526012357403.post-88185229496336435732017-08-29T00:47:50.950-04:002017-08-29T00:47:50.950-04:00So bring a bucket of salt water with you when you ...So bring a bucket of salt water with you when you go to the game store to buy dice.
