Good question, I think that maybe it could be repeated because it would be useful, for example something like this:
5 min -12%
10min -10%
So we see that there was a total decrease of 22%
Or if it were:
5 min -12%
10min 10%

We can see that there was a rise followed by a descent.

But let's see what the other people in the forum say, I'm not sure if it's the best solution..
