37
After 250 rolls I can honestly say this D20 is the worst of the 17 I tested
(files.catbox.moe)
Out of 250 rolls 27 were 1's. A roughly 11% chance of rolling a 1 on this die.
For those curious about the rest:
Here's the stats for all 17
Dice tower
Specifically this one
It's got a spiral staircase from top to bottom for the dice to bounce around
How about data entry? Paper, text file, or camera and image recog?
I looked at the results of each roll and then entered it directly into a spreadsheet
The stat cards are generated straight from the data
Using some formulas in the spreadsheet I tell it to see which numbers come up in a range of cells, then count each instance of the numbers, then order the results in a table from most common to least common.
The averages are generated in a similar way. Basically I tell the spreadsheet to add the number of cells that have data in them in a specific range together, then have it divide by the number of faces on the die (the magic number here bugs me but I'll let it slide for now), and then it puts the result into a cell.
