The BD+C v4.1 guide states that "Exemplary performance is available for projects that test for the additional target volatile organic
compounds specified in CDPH Standard Method v1.2-2017, Table 4-1 and do not exceed the full CREL
levels for these compounds adopted by Cal/EPA OEHHA in effect on June 2016" 

How many of these additional VOC's do we need to test for in order to get exemplary performance?
