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).

Realtime statistics are collected all the time, but they are not included in the report for the pre-sampling piece.
So you can see them while the job is running, but once it is in the report, they are thrown out.
