https://gladiator.tf/listings/60c0e57e7821161b07f09a3c - Scattergun was ~40 at the time of the sale, so 40 should be used as the scattergun price. Its a bit counter-intuitve since the scattergun price just got refreshed at 42 but at the time of the sale the aussie buyer could only get 40 for it, so 40 should be taken. This makes the sale 34.

Both sales sold quickly. I think I would go with a conservative drop to 34 flat.
