I’ve been using CATCount since 2004 and I find it really easy to calculate my fuzzy matches each time. Below is a screenshot from my “Generic” scheme. Depending on your client’s needs you can customize your scheme and calculate the total word count as if it was only one number.
Regarding Reps and 100% matches, I always explain to my clients that I charge 10-20% for all translations that have not been produced or proofread by me. Some of them agree, because they know that their newly-created TM will be of high quality.
