System Recovery Boost SMF record to know how much CPU used in ZIIP instead of GCP

During System Recovery Boost (SRB) some work, that is not eligible for zIIP, is dispatched on zIIP's in case there isn’t sufficient standard CP capacity available.

There is existing SMF to count how much there is zIIP eligible time spent on CP's, for example in the field SMF30_TIME_zIIP_ON_CP. 

But  there is no similar SMF field for the non-zIIP eligible time consumed o standard CP's during the Boost period.

    I do a mistake, i want to write : But  there is no similar SMF field for the non-zIIP eligible time consumed on ZIIP  during the Boost period.
