If I understand what you're trying to ask, you're looking for:

In:       Current: 120.53MB/s  Average:  20.12MB/s  Max: 125.00MB/s
Out:      Current:   1.00 B/s  Average:   3.00 B/s  Max:  10.00MB/s

and so on.  In other words, you need alignment of the text.

So, why aren't you using the formatter string to specify a fixed
length for the numbers?
