I have done gold and silver rolls on every server since the start of the season pass because I wanted to track and see the result of thousands of rolls.

So far I have tracked 18,621 daily dice rolls.

My simple average for all of those is 50.75
My simple average for all gold rolls is 51.15
My simple average for all silver rolls is 50.41
The different servers range from the lowest 49.97 to the highest at 51.40 combined silver and gold rolls.

My rolls of 99 or 100 is 1.8% of my rolls
