Best and Worst spinners

In 4G we had a look at four spinners:
Which one would do "best"? That is, if you were spinning for moves in a game, which would take you furthest? And which would be worst?

We discussed this, and wrote down what we thought:
Then we tried it out. We spun each kind of spinner 25 times, and, using Cuisenaire rods to keep track, we saw what total score we got:
Here are our results, and some of our thoughts about what happened:
We noticed that the 2-4-6 spinner did best both times. Rhea, Hannah and Tibo shared ideas about why this was so:
This one has just even numbers.
But why did the bottom left one only give us 81 (two times!)?
