Clearvue have done extensive testing on the Product, I would think if you called them they would pass you onto someone that could quote all the data results to your questions.

I would think they havnt published this data because it would depend on all the different parts of the earth that would get different return rates,

Also the Aspect , North, North East, North west, West, East etc. Because these angles would make a different return rate at different lattitudes.

So you would have to call them and ask, to get the direct answers to your questions.
