Now that's why I love the internet; meet the guy who wrote the book. I was glad to see in the exerpt you posted from your work that you also tested the Pietta, the only manufacturer of new Le Mats that I know of (and the people who made mine). When I finally get to shoot my new gun I'll post a range report. It'll be more enthusiasm than technical knowledge, but I guess it's always good to get another data point.
In case you don't already haunt the place, there's another great bp forum you may wish to check out:

Wayne and Smokin' Gun are regulars there. It's a pretty active forum with some knowledgable shooters who like to share their info (and bad jokes).
