My rolls are bugged

So, I've had extreme difficulty in ALL of my rolls. I have not but one time in about 500 rolls had anything decent at all. All my rolls tend to be botches or below 10 no matter the bonuses. Even my GMs are saying something may be wrong. Was hoping to have some help. Thanks!
Ok... so I'm not supposed to let y'all in on this... but if you subscribe, you get a hidden bonus to your rolls. It floats a little, so you're not always rolling high, but it's better than what you get as a User instead of a Mentor. >_>

Because a text medium doesn't convey tone very well, I'll point out the previous response was using the sarcasm filter.
Awww... yer no fun. ^_~
Use this to break the random seed, it sometimes works, roll 1d100 before your game rolls. In some of our games this has proved to help restore a better randomness. A few of our players will attest to that.

While this has little to do with how your rolls are coming up in roll20 I just thought I should point this out: There will usually be a difference between number generators and physical dice. Unless you are buying precision d20s your d20s are short on one axis (which is supposed to be the 10-11axis so that you are rolling 10s and 11s more often) and may be weighted. If they are not short on the 10-11axis (short on a different axis) you will get the short axis numbers more often. If the d20 is weighted you will get the numbers opposite of the weighting more often. Both can be tested. Use a micrometer to find the short axis. Use an extremely high saline solution to float the d20. Spin the d20 and if, at the end of the spin, it rolls over in a different direction from the spin direction then it is weighted. Some dice roll over amazingly fast. Here is some additional information on non-precision vs precision dice: <a href="http://www.gamescience.com/" rel="nofollow">http://www.gamescience.com/</a> - Gauss
One of my players is reporting, after considerable testing, that things aren't working out very even statistically speaking. They were far more weighted towards the low end. He literally roll 1000 d20s, one at a time, and recorded the results. I'll get the actual numbers from him when I get the chance and put them up for you guys. Hopefully it will be helpful. EDIT: Here are the roll results. You can see that something is kinda off for the 2-7 result. He promised to try it again when he has more time. 20 (2) 19(6) 18(10) 17(11) 16(30) 15(12) 14(27) 13(55) 12(40) 11(21) 10(73) 9(82) 8(30) 7(75) 6(91) 5(210) 4(67) 3(56) 2(81) 1(21)
This has come up before , but in the interest of checking to see if something has changed, I decided to re-run some tests. 9990 rolls each of d20 and d100 produced the following: D20 Average: 10.5 Stdev: 18.03359438 D100 Average: 50.5 Stdev: 9.888775394 Now, the stdev for D20 is a bit higher than I was expecting; it's something I've asked the devs to look into. However, fundamentally, I think this issue comes down to the fact that random numbers don't seem random to humans, especially in 'small' sample sizes. It's an issue any software with random numbers faces: VTTs, video games, etc. All that being said: Sarah A, the numbers you posted do seem rather skewed. Do you think you could ask your friend to get another (preferably larger) sample size? We would like to know if there is some other factor that could indeed be skewing the dice roller. Thanks!
Thanks for the info, Balladeer. I can indeed ask him to roll another set for you. He was planning on it anyway, but won't have the time till the weekend is over. I'll let him know. He did want me to point out that when he used a macro to roll all 1000 dice, it was actually pretty even. Rolling them individually, one at a time, was when he started seeing the skewing of the results.
