I've seen other posts with as low as 52 of each of the blue samples. That's kind of why I said 9 stacks of data samples instead of 30ish trades. The stacks max at 50, so 100 of each red is 6 stacks and 50 of each blue is 3 stacks for 9 total.
Is there evidence to suggest that the amount doesn't depend on the type of resource? I.E. that 9 stacks of 'red' would be equivalent to 6 stacks of 'red' and 3 stacks of 'blue'?
