So what I was thinking is that sure, the line 

```
 result = report[-1][2:].strip()
```

tells me what happens. 
Index -1, so that's the last element, i.E. the last line. Then slice starting at 2, so that's everything on that line except for the first element.

But it doesn't tell me the intent. 

Why do I skip the first word on that line?
That could be cleared up with a named slice and a variable, e.G.

```
CRAM_SUMMARY_LINE = -1
CRAM_LINE_WITHOUT_LEADING_COMMENT = slice(2, None)
result = report[CRAM_SUMMARY_LINE][CRAM_LINE_WITHOUT_LEADING_COMMENT]
```

Of course my example is a bit extreme. I think a shorter name would be better. But this is what I meant. I also don't think it is really important to change, it all comes down to personal preference.
