In Traveller, misjumps happen for one or more of the following
reasons:

1. jumping inside the 100 diameter limit
2. missed maintenance on drive
3. using unrefined fuel (unless drive is designed for it)
4. damage to ship/drive

Given that, there's rarely anything that needs much explanation. The
first three are *all* avoidable unless there's an emergency, and even
then, it's a "you knew it was dangerous when you did it" situation.

The last is one of those "what can you do?" situations.

*None* of those reasons are guaranteed to cause a misjump (well, the
last could be depending on the specific damage). But all of them
result in an *greatly* (one opf of six?) increased chance of a
misjump. and they add together. So jumping inside 100 dia, using
unrefined fuel and missing maintenace gives you a 3 out of sic (50%!)
chance of a misjump if I'm recalling the rules correctly.

Things are a lot worse for jumping from inside 10 diameters, but I
don't recall the rules for that, just that iot's a truly desperation
move.
