Your sale on the sunbeams ninja must be in-date, that is, within the last 4 months. If it’s older than 4 months, it doesn’t count until you find a sale that is less than 4 months old. If your sale is actually in-date then you need to provide proof and use that as the value of the sunbeams ninja, that’s what a mini is.

For the brain warming, you can’t just assume the value is 50 based on bot buyers and sellers, you need sales to confirm that is what it gets. If you’re using unpriced items in a price suggestion, you need to definitely verify their value to make sure the hat you’re pricing isn’t priced incorrectly, hence why the unpriced item needs sales to be priced accurately. The buy order is representative of what people are willing to pay at minimum for the hat so it can help in deciding its value using sales. Also you should only round values after the final value is calculated so there’s no mistaken rounding.

I don’t want to antagonize you or your suggestion, and I’m still new to the rules, but that’s my opinion based on what I’ve read!
