Like Webby mentioned we won’t know until it is tested.
I am also curious.

Just to clarify a few points made earlier:
1. Real-world pump testing (DDC 3.2 and D5 were mentioned) would provide useful information. Gabe is under no obligation to provide such results.
2. Gabe's information is useful in that it adds to the growing knowledge base concerning these two blocks, even if he chose to provide information using a pump none of us use in our builds.
3. Gabe's information, although from a potentially biased source (despite his long track record of providing good, verifiable information), is produced in a manner that is both easy to understand and free of typical variables.
4. Crying out for "real world" test in the manner that has been done in this thread is begging for configuration-specific results that are not universally applicable.
5. No test, other than one you either conduct yourself or hire someone else to do with your specific hardware, will be 100% applicable to your system. None.
