I'm used to the user exit format for CPU timings:
where the TCB and SRB times are separated. My apologies for not realizing the format of the OP's message wasn't the same.
However, the bottom line remains for the OP -- yes, SRB time went down but the overall CPU time went up. As shown above, SRB is typically much lower than TCB (although the SRB usage depends upon how the program is using system resources), but both are CPU time and are combined to get total CPU usage.
