My guess is that -probably no. It's more likely you had a stream of good luck in your earlier interactions and now you're observing regression to the mean.
That can easily happen and it's why, for example, medical studies, are not taken as definitive proof of an effect.
To further clarify, regression to the mean is the inevitable consequence of statistical error. Suppose (classic example) we want to test a hypertension drug. We start by taking the blood pressure (BP) of test subjects. Then we give them the drug (in a double-blind, randomised fashion). Then we take their blood pressure again. Finally, we compare the BP readings before and after taking the drug.
The result is usually that some of the subjects' BP has decreased after taking the drug, some subjects' BP has increased and some has stayed the same. At this point we don't really know for sure what's going on. BP can vary a lot in the same person, depending on all sorts of factors typically not recorded in studies. There is always the chance that the single measurement of BP that we took off a person before giving the drug was an outlier for that patient, and that the second measurement, that we took after giving the drug, is not showing the effect of the drug but simply measuring the average BP of the person, which has remained unaffected by the drug. Or, of course, the second measurement might be the outlier.
This is a bitch of a problem and not easily resolved. The usual way out is to wait for confirmation of experimental results from more studies. Which is what you're doing here basically, I guess (so, good instinct!). Unfortunately, most studies have more or less varying methodologies and that introduces even more possibility for confusion.
Anyway, I really think you're noticing regression to the mean.
