due to the fact that users frequently publish good and useful topics but no one gives them the benefit until it becomes like casinos rely on luck.
This has been brought up many times before. It's impossible to properly quantify since awarding merit is completely subjective, but all available evidence is that this simply isn't true. There are several merit sources who spend a great deal of their time searching for good, unmerited posts - they are few and far between.
If you do find good posts which you think deserve merit, please link to them in this thread:
[self-moderated] Report unmerited good posts to Merit Source. Looking through your post history though, roughly half your posts seem to be in Off Topic - this board has one of the lowest merit-per-post ratios because it is so full of spam. I would suggest you will have a hard time finding many merit-worthy posts in there.
