nice graphs! can you use it to check if you are getting the amount of coins you should get based on your hashrate?

[json output]
the help may be a little misleading on this one. the only json modifier for -r is screen. the same goes for -o. for clocktweak to write something to a file you need -o and -w. then you can use all the json modifiers.

the single entry files will be stored in the clocktweak directory, the log files will be stored in a subdirectory "logs".

if you want a single read run and json output you can use a command like this:
clocktweak -r -n -j screen > ct_read_j.txt
