Re-suggestion, fixed the range.

No sellers/buyers on bp.tf, no recent sales at mp.tf (most recent sale 1 september: 2 sales @ $100, probably spelled)

SCM sales Past 2 weeks:

21.40, 26.25, 28.36, 32.05, 31.87

21.40 is lower than most sales in past 30 days so not counting it.

26.25 / 2.24 = 11.72

28.36 / 2.28 = 12.44

32.05 / 2.30 = 13.93

31.87 / 2.37 = 13.45

The range is 11.7 - 13.9 keys.

Also 3 year old price and 4 rejected suggestions in a row.
