The statistics of single WFO cycles are not sampled. You could either calculate them by script, or use NumTotalCycles and run a single WFO cycle only. Then you get the statistics of the cycle.

Oversampling uses BarOffset only. Anything that affects bar generation, like BarPeriod or start/end dates, cannot be changed in a TotalCycle. The rest, like DataSplit etc, can normally be changed. Try it.
