The 30 letters on top equal the ???/780
LLOLZGODSMMUARKXKAQTECNTJKSCT - 240/780
Take out the repeats
LOZGDSMUARKXAQTECNJ
Change into numbers A=1 B=2 etc
12-15-26-7-4-19-13-21-1-18-11-24-1-17-20-5-3-14-10
Add all those numbers together and you get 240

TQUDMWJXVEKPFGRSYOH = 20-17-21-4-13-23-10-24-22-5-11-16-6-7-18-19-25-15-8 = 284

I've done this with several more but yours doesn't seems to work. "YMAGTMRCXGHQDHNLMQEHBCMVAKPCZG with 271 / 780"
YMAGTRCXHQDNLEBVKPZ = 25-13-1-7-20-18-3-24-8-17-4-14-12-5-2-22-11-16-26 = 248
Also, the "counter" is just your computer's clock. I think the clock somehow determines the ???/780 but I havn't found any proof of that yet or how it works.
