I agree, also they have to be near misses. You have to get pretty close to get credit for this UFO feature. I completed it to get a UFO once since this feature started. I don't think you ever get a credit on the same level twice? But I might be wrong as usually if I find I can't complete a level I just quit and retry until I get close enough to either pay 10 gold or use one of my own boosters.
