Legendary sale. Congrats.

Aside from the fact that this sale is definitely an outlier in realistic sense, there's a couple of major issues here.

The first one is the AF KE, which as pointed out has a mini that isn't valid. That won't be that far off I suppose, but it may be worth looking into that.

Other sales there:

Duped scorching TC, by guesstimate that'd be 600-700 ish, but would need some looking into

Demon vive, stormy 13th tyrants, cbubs veil and the hard counter

https://backpack.tf/profiles/76561198803829026#!/compare/1537056000/1537142400

https://backpack.tf/profiles/76561198043991016#!/compare/1537056000/1537142400

That's a little higher than the currently proposed mini

Sold for the hats here - TC's duped and probably way too high. Most recent mp sale is around 230 keys

https://marketplace.tf/items/378;5;u64

Would make the sale 700 ish, and thats taking the cotton at current (which was updated conservatively)

AF vive, PE muffs and dbd modest

https://backpack.tf/profiles/76561198021272428#!/compare/1538784000/1538870400

That's significantly lower

Sold for the hats here. Tower needs a drop (recent suggestions have been around 90 and only had minor flaws) and so does the buto (seller at 200)

https://backpack.tf/profiles/76561198198247314#!/compare/1533600000/1533772800

I guess the sale'd end up somewhere around the used mini though

That's all for the law mini; only other law sale is a bulky sale for a strange burning warpig which has no other sales other than a bulksale for a duped burning TC (which Ill mention below), but indicates that it may be on the high side. But then again, its mainly the other two hats that are going to be dealbreakers here.

Then there's the beard. The sale used in the mini here is probably an outlier altogether. That was resold in aforementioned bulksale for the duped burning TC, and has since be unsuccessfully selling for 600 (and recently even lowered to 550) https://imgur.com/a/8Icec82

The TC sale:

Other sales there are mediocre in usability, but all share a common ground in that they're much lower than the sale used here (and even than the seller listed).

It sold here with adds (little over 100 directly match) for a GE boa (has sellers at 500$ which is sub-300, and other sellers supporting that needs some serious drop) and a cauldron TC

https://backpack.tf/profiles/76561198218497692#!/compare/1532563200/1532649600

That TC has sales here at what seems to be 119 keys?

https://backpack.tf/profiles/76561198112516663#!/compare/1535155200/1535241600

I doubt thats all thouhg

it has another sale here for a DaD crown + beams air dog

https://backpack.tf/profiles/76561198218497692#!/compare/1534118400/1534204800

The crown was conservatively updated and had a seller at 300 when it was last accepted. That'd need looking into as well, but even taking that at that seller's value it'd make the sale 330, and the total of the beard sale at ~500 ish, and it is not unlikely that both hats are still overstated in value there.

Then theres this:

https://backpack.tf/profiles/76561198037248506#!/compare/1532217600/1532304000

The RA modest's only sale is far far lower than current (though thats probably too low). Taking that at 300 would make the total of the sale 500, and at the open suggestion's value, or what it would've been if the houwar was properly assessed, it'd make the beard just a little over 300

There's also this (currently outdated though)

https://backpack.tf/suggestion/5adfb79644325a73771252c7

Back then that'd have been a bit lower than what it was suggested at also supporting that the sale used here would be an outlier over a larger period of time. Not direclty usable as evidence of course, just looking at everything I can here for this rather odd case. (and it's still more recent than the gibus, see below).

Then there's the gibus, which is definitely not in-date. the suggestion isn't even in-date, and the suggestion was based on a sale from march and a 3-month unsold. Recent sales are far lower:

https://backpack.tf/profiles/76561198079333678#!/compare/1531267200/1531526400 280 keys

https://backpack.tf/profiles/76561197971390626#!/compare/1532217600/1532304000 with searing pusher for 350 keys (so ~290-300?). That'd make the gibus over 200 keys too high here. aside from that it was also dumped in that bulk for the duped burning TC along with all the other overpriced hats

You really can't rely on sales from march on that; I mean, if we're going to look that far back on thís hat, we'll find that aside from this sale, the most recent sale supported current instead of this

https://backpack.tf/profiles/76561198118859180#!/compare/1522627200/1522800000 (and at that time the rota was 450 so it'd even have been lower :P)

Again, that can't be used directly, but it should be noted that this sale for the mohawk is 100% an outlier in reality.

All in all based on the above, this will likely be over 400 keys off, and that's even ignoring the fact that you're using a taunt without a proper mini (the sale used is fár too old, again if we're going that far back, we can see that at that time the mohawk had another sale that supports this being one big outlier :P).

I'm generally hesistant when it comes to this update (mainly based on the fact that the sale is 3-4x higher than any other sale ever), but if it is to be done, it's gonna be needing a lot more work
