Conclusion

A little adjustment from that hideous 3 (2.9) bud range. As you can see, there are 4 sales/solds, and these solds were the only solds for this hat ever, just check out its history. Current owner is looking for around 8 buds, which proves even more than 8 is an outlier. If that doesn't, then look at the sale at 5.4, 6.2 and 5.7* and tell me that it's not. Range is a nice 0.8 buds, not a silly 2.9. As long as Unknown doesn't get the rep hurr durr. Any Extra Proof/Cunter-Proof/Opinions/Tips/Help is all welcome. Thanks for reading. Feedback is always appreciated.
