hi, I wasn't able to find an answer to this question. If you are stuck and you think this information should be available publicly, I can ask the author. Best, newton

Thank you for the quick response. It would be very kind, if you could ask the author because I guess, that the computer will be very busy for a very long time to solve this challenge and I would prefer not to doubling this time due to a wrong KTF selection.
