Hi, I’ve had this question a few times.

 ![image](https://d2a8kmyc1dvkyq.cloudfront.net/original/1X/00d86d0be0fbd1ed57ef667f3941e24658e5fc56.png)  
everytime, the percent has been 15%.  
Wondering if that should be a random variable but is coded as a fixed constant instead.

Hey @James1, thanks for flagging this one. I’ve double-checked the randomization logic, and it does have an equal chance of drawing a number between 15% - 40% in intervals of 5%.

It’s crazy how the randomization can lead to seemingly non-random streaks!

If you have some time for a fun (in my opinion 😉) dive into it, take a look at this:
