This kind of thinking is wasteful. Every d20 has a finite lifespan. It was created, and it will, at some time in the future be destroyed, as all things are. That means it has a finite number of rolls in its lifetime, with an equal distribution of all possible outcomes. When you “practice roll” and get a nat 20, you have wasted one of the limited number of nat 20s that die has in it. Think of the 20s. Don’t practice roll.

Tigers are only CR4. There’s lots of stuff more dangerous that that.

Some good ideas here, but if I did this with my group, I’d have to deal with them volunteering for the process.

That looks like an IBM PC. I recognize it from my childhood years when the father of a friend (who worked for IBM) had one in the early 80’s. That dude is probably as nerdy as he looks. So not a dumb terminal, it’s one of the first home computers.
