I'm testing with the divisor keys on a smaller range, but its not solving the key with keyhunt. does it work the same with xpoint mode?
you need to adjust K and N as smaller range will be not solved if power of K and N is more than range count or if number of keys will be more or less than power of your hardware.
remember tweak is seriously needed while keeping K and N according to your hardware power as well as adjust K and N according to number of keys you will load in software ~ do the test again and again and again
