Question about calculation averages

[Zamasu_Chan]

So I was thinking, are we allowed to find an average between a low end and a high end of a calc?
For example, I make a calc with a low end of 0.25 tons, a mid end of 5 tons and a high end of 9 tons. The average of all those yields would be (0.25+5+9)/3 = 4.75 tons.

Can we do this, if not, why?

We don't do this, because high, mid, and low ends come from different assumptions set during the calculation. Which one is accepted would be based on which set of assumptions are the most reasonable. Averaging them out both negates this and produces a result that doesn't match up to any set of assumptions at all, which is weird.

Ah I see. That makes sense.
