History for the Con Cap - https://backpack.tf/item/2765230702 (As it doesn't feature in the compare link)

The Conn Cap seems higher than 29 with Buyers for ~32 Keys (Clean ones haven't been traded in ages) and the sale you're using on the Muffs works out ~34 Keys (Even though it's slightly bulky too) https://backpack.tf/profiles/76561198286485732#!/compare/1537315200/1537401600

The Exec mini is too high also, 1 Month Unsold at 38 Keys and a 4 Day seller @ 33 Keys confirms this, I'd look into a better mini for it

Right now you have sales at 29, ~34 and the Exec Sale (~30 ish) so you can give this a range. The unsold is really young too so not sure why you excluded the other 2 sales like that but this'll need re-working
