They backed this up by giving me several examples of real customer's keywords
In other words, they gave you a list of keywords that they already knew ranked well for those clients. Those keywords may or may not be the best keywords for those clients- they just happen to be ones that rank well.
The real test would be testing with keywords that you (or other people) would actually use when searching for that type of business.
