No problem. Glad to hear that it was useful

  1. No. You can find a more detail explanation here.
  2. If you wanna increase your performance you could try: increasing your calibration dataset or modify your .alls file. More info for option 1 and option 2. Note that both solutions will increase your compilation time and demand more resources
  3. Sorry, I didn’t understand the question

Hope that helps
