i don't understand this suggestion

If something has a 2 year old price, then you need to find sales for it (called a "Mini," as in mini-suggestion) in order to have a valid price for it. That said, the Ooze Hive has no recent (within 3 months) sales, so you can update it using the first sale here. Additionally, the Burning Hive Minder doesn't have great sales to use as a Mini, so you can update it using the second sale here.

That said, there are a couple sales you've missed:

https://backpack.tf/profiles/76561198252999692#!/compare/1568332800/1568592000 - Pro KS Australium Rocket Launcher (~48 Keys) + 3 Keys

https://backpack.tf/profiles/76561198065400580#!/compare/1569196800/1569369600 - Sunbeams Hermes + DP Tavish's Crown + 6 Keys

https://backpack.tf/profiles/76561198286257338#!/compare/1574812800/1574899200 - Bulk sale (the Boron is <50% of the trade's value)

https://backpack.tf/profiles/76561198055622215#!/compare/1575590400/1575849600 - Also a bulk sale

https://backpack.tf/suggestion/5ddf0eb0678072451b3a9bdf - The Sunbeams Hermes is looking to be somewhere around 40 - 45 Keys

https://imgur.com/a/W4Q2MjJ + https://backpack.tf/item/7955533388 - The Tavish Crown has a Seller at 11 Keys

That sale will end up around 60 Keys.

The sale at 51 is very close to Buyers, so it can be excluded as a low sale. Thus, the Hermes/Crown/6 Keys sale is the only valid one, but the refresh at 60 isn't really necessary, so I'd close this suggestion and leave the Boron with its 3 month price of 60 Keys (the Hermes/Crown/6 Keys sale happened less than 2 weeks after the last suggestion was accepted).
