You really should leave rounding until the very end:

https://backpack.tf/suggestion/606a1098a3ae85214451d39d - 27.5

https://backpack.tf/suggestion/605c519539956b23946e1a6f - 37.5

https://backpack.tf/suggestion/6087121651898d1a891a7201 - 23 (not 22)

6 keys

27.5 + 37.5 + 23 + 6 = 94 keys

This will probably just be "close enough"

Dumped next day

We have a buy order dump for 98 keys to zol, who was like 20+ key above the next highest buy order at the time

GE Seared that should come out to ~90

75 keys

and then your purchase for 94 keys in items

There is currently a buyer at 90 keys so I'm inclined to ignore the GE seared since Lemons hasn't got around to resuggesting that.

Given the pure sale at 98 keys to Zol, 94 - 98 keys?

Mean of 96, so it's a 3 key difference but it has a range to suggest that there was more than one sales since 93 keys by itself is rather deceptive.

Up to mods what should happen, this is probably fine as is but I'd much prefer a pure sale in the range as well as correct maths.
