There's a known bug with ratio metrics right now that we're trying to figure out. We use the Delta method to estimate the variance of the metric. In some cases, this estimation process can result in a negative number, which breaks our statistics engine

Hi @future-teacher-7046 I also see even I don't applied the ratio metrics still the metric result start with negative number. Ideally it should start from 0%. Its also the part of same bugs?

That graph shows the results at the end of each day, not the start. I guess we could add an extra data point at the beginning to force it to start at zero.

But the experiment start on same nov 6 so ideally it should be at zero.

What the graph is saying is that after that first day of data on Nov 6 came in, the variation was losing by 30%

Ok! then I think this would be greate

@future-teacher-7046 kindly update once the bug resolved related to ratio metric. Thanks
@future-teacher-7046 when we go to view query and we see results as table. The column for metric results count is also no more there. is it bug or removed by the team?
