Buyers up to 4.55 keys,

seller at 8 keys,

given that there are only two buyers (that I can currently see) for 4.45 and 4.55,

gonna call 7 high,

4.2 and under low,

taking 4.25 - 6.5 to include the most sales.

due to the average being greater than 5, 0.5 rounding rule applies,

taking 4.5 - 6.5 keys.
