Division by zero in convergence test if yMax == yMin, about triscale HOT 2 OPEN

Thanks for reporting!

Indeed, if all elements are the same, the empirical evidence for "has converged" is as strong as it gets :-) I'll add a test case for that.

from triscale.

On further inspection, the problem occurs for metrics only if:

1. All data is equal AND bounds are not set, or
2. Bounds are set by user to equal values (which raises other questions)

The issue is present for all invocations of convergence_test(). E.g. for KPIs it occurs if all values are equal (as bounds are always set to max(), min()).
