Rolls Abysmally Low

I noticed that for the majority of the time, my rolls are extremely low -having rolled three critical failures in four turns, with the one non-critical being a four. I roll a 20 maybe every 80 rolls and I am consistently rolling below 10....with an occasional 14 here and there, but almost never 15+. Is there any reason behind these inconsistent rolls aside from sheer bad luck? I don't have any special features on but it's beginning to become really frustrating. (Sorry if this is in the wrong thread btw, wasn't sure if it was considered a bug or not)

What you are seeing is a truly random rolls. There is nothing to influence the rolls in anyway. This thread was dedicated to a long discussion about the roll engine :  From The Source - Roll20 RNG Testing

To add to the RNG thread Metroknight posted above:  Real dice are biased and not truly random. Most d20's are short on one axis with the axis that many manufacturers keep short being the 10-11 axis and the long axis being 1-20. This will produce results that skew away from 1-20 and towards 10-11. This can be tested using a micrometer. In addition, many of them are weighted. This can be tested by floating a die in salt water and spinning it. At the end if the die changes direction it is weighted. The harder the direction change the more it is weighted. - Gauss

A test you can do is go into a game and type /roll 1000d20  See what you get. 10000 is average. I just did it and got 10106, meaning very even. meaning i roll 10.106 on average try it out just to see what you get. This is no way says anything about roll 20. But could help out since odds are you havent thrown 1000 d20s and could be surprising.

It happens to some of us. I'm a terrible roller, but I know a guy who crits every game. Every game! I'm not joking. How in the hell can a guy get that lucky? One of my players last game missed five times in a row, while others rolled super high. It happens, and it sucks. I actually roll better with Roll20 than I do when I roll real dice. It's actually pretty satisfying at times.
