Regarding the ore concentration overlay

[Drillgorg]

Hi, question about the ore concentration overlay. Why is it that I can scan all the biomes on a planet/moon with ground scanners, and yet if I set the cutoff to say, 70% there will be no ore? Shouldn't the cutoff show the highest concentration on the planet/moon as 100%? Should I be using the narrow band scanner? Last time I used it, it didn't show very much detail.

I've been trying to find a concentration over 8.25% on Ike.

Once you have done ground scans of all biomes the narrow band will be 100% accurate. The 70% thing I don't know for sure but it's probably saying that there are no medium sized regions which have an average over 70% of the highest value found on the body. Try using dots, this is the most accurate orbital overlay.
