I think this may help with my issue, however my 4th word is not a number. It is a letter. See attached Image:
As it is the letter C. I am wondering if it is changed to say E or G if that would increase the time?
I should have noted that in the wiki -- will adjust when I have a bit more time. These numbers are hexadecimal, so in your case, C represents 12, and 2*12=24. Convert back to hex, and you'll get 18.
Quite a few calculators (both on your Desktop and real physical ones) can do the conversion if needed.
Basically, decimal has ten digits 0-9, hexadecimal has 16 digits from 0-F. So, decimal 15 is hexadecimal F. And decimal 16 is hexadecimal 10.
BTW, I would stick with doubling or tripling the original sequence, so 0018 or 0024 for you. Don't forget to copy everything after that fourth word once or twice at the end.
Hope that helps!
