I think this might be it:

If this applies, then 8,000,000 samples over 10 minutes is the default. 

I would note that it might actually take a couple of minutes before the cap was 
activated. It is a running average, so it would take WLM a lot longer to react 
to an abrupt increase as opposed to a slow ramp up. That doesn't matter since 
you are billed at the actual R4A or the cap value, whichever is lower. 

Wonder what the manager really wants to know? 

HTH and good luck.

Subject: Re: Softcapping Q: Where is the sample interval for the 4hr rolling 
average documented?

Resent plain text, sorry for the formatted one previously.

Someone in management here wants to know what the sampling interval is
for the calculation by the z10 hardware of the 4hr rolling average MSU's
that is used to trigger softcapping.

Would one of the performance gurus here please point me to the FM where
I can find this information for z10 EC machines?

TIA for your assistance.

Peter
