20 keys? the keys come from keyvendor so its possible they were bought then used

most likely 20 since buyout was also 20 https://gladiator.tf/listings/60f7839a9e71c00c86bffd47

20-33 seems a bit too wide

The user who bought it for $63.33/28 key buyout later sold it to qs.store

The first 33 sale on MP took less than 2 weeks to sell, while the 25 key one was listed

The one I bought for 25 resold for 33 in less than a day on MP

But it was up for almost a month, listing here at 25 on August 14 https://gladiator.tf/listings/611878226a9837f4418c73f2

28-33 are all MP sales

Going with 20-25, not that 33 is too high right now with 3 sales at it, but this range seems more appropriate than 20-33 or any higher variant
