Will statistics be collected during the pre-sampling phase? (4363937)

Will statistics be collected during the pre-sampling phase?
According to the Benchmark Factory (BMF) Online Help no statistic will be collected during the pre-sampling phase.

Pre-Sampling: The length of time users execute transactions in order to reach a steady state before statistics are collected.
Sampling: The length of time to collect statistics while the users are executing transactions.

But if a job is running and I switch during the pre-sampling phase to the "Realtime Statistics" I can see a graph there (see attached screen shots).
