How many points do scales give?
 

Hello*
i need to know how many reputation points do scales give when choose "I aprove".
And most important - how to chage scale to give 1 point per use?
The problem is that for 2 years my users used only post hack button (gives 1 rep point) to make reputation and green bars and now for 2 weeks most of them got max green bars with "scales". And i don't want to remove that feature because of negative usage.
Now i want to recalculate their real reputation and rep power points!
Thanks!
