I think we are giving marks on the quality of our article. If our article is the best one and it contains useful information, it will get the highest points and the cash credits. But if our article contains only descriptive information which is not of high quality, less points and cash credits will be allotted to it. If any new member writes an article, he will get the high points and cash credits because the points and cash credits may be for his encouragement. So if you have got points 100, 60, 50, and 25 for your articles, it means your some articles are useful to us and it has unique information. This is of my own experience and this is of my own words. I think some responsible member like editors or our respected webmaster will come in the Forum and response to your query. So we should wait for it.
