Is a 155 throws enough to evaluate bias? Seems more times than I'd like to roll some dice, but not enough to gain enough measurement confidence. By what criteria is the person assigning the traffic light ratings? What about face coplanarity? Get this enthusiast in a metrology lab.!

Sounds like a very fun hack project to build - automatic dice evaluator.

Wendell at level 1 techs built one for Steve of gamers nexus! It was interesting. I was going to link the video but couldn't find it, sorry.

No, it's not enough. Maybe if the bias is 10% or more.

No, it's much too low. OP shows Pearson's X^2 for their results, but that alone is meaningless. p-value would be the interesting metric. I haven't computed it (although we could from the results) but I expect it to be very high, i.e. it's likely to observe these results even with perfect dice.
