Boost hours easy

I know all of you knows to boost hours with steam idle or daddy iddle.
What I exactly do:
First you must to download SAM(steam achievement manager)
Open and go to CS:GO and double-click on icon(into SAM)
Go to stats click on I understand by modifing....
Go to time played and increment time.
Its best my example
I have 819 hours its near 1653260 and i change 6 to 8 and now its 1853260
Click on Commit Changes and open CS:GO normaly
Play CS for few minutes and exit
Now I have 863 hours

Profit: For only 5 minutes i have 43 hours more

I dont know English good
