According to the backpack.tf calculator, 5 keys+10 ref = 5.67, which should be rounded up to 5.7

If you do re-suggest, re-suggest at 5-5.7

http://www.tf2outpost.com/trade/24828981 - closed due to inactivity and then relisted - http://www.tf2outpost.com/trade/24935082

it's hella young though.

http://www.tf2outpost.com/trade/24867953 - 4 days unbumped

http://www.tf2outpost.com/trade/24863011 - unbumped and set his backpack to private so we'll never know whether he sold it for not.

So you should resuggest but here, things get a little complicated:

From your links:

http://www.tf2outpost.com/trade/24911958 - 5.4 vendor sold after 2 days

http://www.tf2outpost.com/trade/24909987 - 5.5 vendor sold after ~2 days

http://www.tf2outpost.com/trade/24867990 - 5.6 still unsold

http://www.tf2outpost.com/trade/24915853 - 5.7 sold

so if you were to resuggest (which you should), it would be 5.4-5.7 BUT let's look at your unsolds:

http://www.tf2outpost.com/trade/24917672 - sold within a day, showing that 6 keys still happens

http://www.tf2outpost.com/trade/24897960 - still unsold

http://www.tf2outpost.com/trade/24876901 - sold but painted so invalid

http://www.tf2outpost.com/trade/24852803 - super unbumped but sold, unsure if this should be used because unbumped but also because there are no keys in his inventory or any indicator as to where the keys could have gone.

what does this all mean? well let's look at the market again:

http://www.tf2outpost.com/trade/24930015 - 5 (young)

http://www.tf2outpost.com/trade/24932377 - 5.3 keys (very young)

http://www.tf2outpost.com/trade/24867990 - 5.7 keys (5 keys + 10 ref)

http://www.tf2outpost.com/trade/24923848 - 6 keys

http://www.tf2outpost.com/trade/24932418 - 6 keys (Robo keys though, that might be a thing)

http://www.tf2outpost.com/trade/24779828 - 6 keys (been open since January 23rd so that might mean he sucks at bumping)

http://www.tf2outpost.com/trade/24205060 - rejected 6 and 6.5 keys

Two valid unsolds at 6 keys and one rejected offer at 6-6.5 keys, so that would scratch out 6 keys from the range

so what does this all mean? Two things:

1) When (because you really should) resuggest, you should do so at 5.4-5.7, you have the sales at not-quacksales so it should be all valid. If you want to really close the gap, you might be able to get away with 5.4-5.5 (that would mean you're implying that 5.7 was an outlier but then this is risky since 5.7 was a valid sale).

2) What the fuck, I have too much fucking time on my hands

Your call.
