Thank you Maggie. I haven't used American patterns yet, I have so many Burda magazines, for me it's easy to take out the patterns. Burda patterns don't have seam allowance. I like them, i think they are well marked I do have to adjust the fit, usually at the waist, but the men pants patterns I used so far, fits Tom perfectly. I will try an American pattern one day, let you know the difference.
