Remove fuzz factor and move ts set before wait
Remove fuzz factor and move ts set before wait

The fuzz factor was too large (5 sec), given that we only wait for 5 ms
between inserts. Waiting 5 sec for the test slows it down too much. So we
remove the fuzz and read the ts before the wait. Since we now do lte, this
should still be fine.
