Am I using time right to measure it?
No, you're timing the cat only.
I don't think that's the case, you know. If I run the following:
[summer@bilby ~]$ time sleep 10s;sleep 10s
real 0m10.011s user 0m0.000s sys 0m0.003s [summer@bilby ~]$ time sleep 10s|sleep 10s
real 0m10.002s user 0m0.001s sys 0m0.003s [summer@bilby ~]$ time sleep 10s | time sleep 10s 0.00user 0.00system 0:09.99elapsed 0%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+150minor)pagefaults 0swaps

I sit corrected, thanks John. A subshell appears to show the expected behaviour...
[wmcdonald@stella ~]$ time $(sleep 10s; sleep 10s)
real 0m20.011s user 0m0.001s sys 0m0.006s
