I wonder if these labels still make sense if negate_differentials is on.

I'm not sure I follow the phrasing here. If, for example, we spend 2x as many samples in some frame, this will look like (I think):
= 2 × old cycles
Which I think is maybe overly concise. It doesn't include the function name (is that printed elsewhere?), and the old or new sample counts. I think we'll want to include at least the function name and one of the two absolute numbers. I'm also not sure if "old" and "new" are understandable labels in this instance (esp. for negate_differentials) — they may even be unnecessary. I think "2×cycles" may actually be sufficient.
