Well, partly, that's the point. It was initially here so that members could see what the camscore feels like to models.
But, it makes sense really. There are a couple things that go into it. One is "how often are your posts thanked?" Meaning how much does the forum as a whole like your posts. The other is "how often do you thank posts vs how often are you thanked?" meaning, do you get out more than you put in, or do you put in more than you get out?
So let's look at the numbers:
of all the posts vlad did, he only got thanked on an average of 1% of them. However, you got thanked on average 147% of the time, meaning each post would have at least one thank with half of them having two, if the thanks were spread out equally. Thus, you have contributed more valuable information.
Now, vlad sends about two thanks for every thank he receives. Thus, he's getting twice as much out of this forum as he puts into it. You, on the other hand, thank a little more than you are thanked, so you put in almost as much as you get out of this forum.
But, why, then is he so close to you? Well, you've been here longer. You are being judged based on your contributions for 60 days, while vlad is being judged based on his contributions for 5 days. If it weren't for that, your score would probably be much higher than his.
This, again, goes back to how mfc's camscore works for models. Model who have worked long hours over the past 60 days would need to make a ton of money to have the same camscore as a model who only worked a few but got tipped steadily for those few, and got offline tips.
