IMO the groups that apologize for using MTL like you do are almost never the real abominations - it's the for profit groups that don't tell you, but obviously nobody involved knows either Japanese OR English.
Sometimes MTL misses a fine point, but you're doing a great job with editing it to make sense and sound natural, so we get 98% of it. Which is way better than not at all or from one of the groups that has 'strenght' in their spell checker (seriously, why is that mistake so common?).
Anyhow, thank you!
