Understood. Is there anyway to do what I want? If not, maybe a useful addition, see https://javadoc.io/doc/org.openjdk.jmh/jmh-core/latest/org/openjdk/jmh/annotations/OperationsPerInvocation.html <https://javadoc.io/doc/org.openjdk.jmh/jmh-core/latest/org/openjdk/jmh/annotations/OperationsPerInvocation.html> for a similar Java api.
The reason this is helpful, is that some algorithms will degrade on subsequent (e.g. the first order insertion is really fast, but they get slower and slower because the dev used an O(n^2) design - a test that only goes to b.N may not hit it. It is also useful when comparing performance metrics for operations like these across languages (similar testing framework in a non-Go language). So you need to be able to test the add operation but calculate the average time per op across the test with a minimum number of elements.
