Trying to understand why there's a big drop in coverage

[Jericho]

Does Codecov offer a way to help us understand why coverage changed significantly? For instance, is it possible to compare the coverage between two given dates?

As you can see in the screenshot below, our coverage had been steadily climbing over the last few weeks but approximately a week ago there was a 5% decrease in our coverage and I am investigating the reason for such a big drop.

I'm sure there is a logical explanation (for example: someone inadvertently removed a bunch of unit tests, several covered lines of code were removed, significant amount of code was added to the project without unit tests, etc.) but I am struggling to find the explanation.
