Foamy's Part:

I would go with a full range here. If 75 took that long, I don't see why it should be treated as an outlier here. Especially since 75 and 85 are far closer to ecah other than 100 is compared to any of those sales.

To complicate this further:

the cowl will be resuggested, so the data point at 100 will change. Normally, that would end up becoming an outlier, but I'd get the issue of this being priced close to buy orders if that'd happen.

At this point I'd wait what happens to the cowl and then either leave it unpriced or give it a giant range

Taking 75 - 115 keys.
