RED has done in house chart tests before without bias. They did an Alexa vs. MX test way back and they provided the test and flat out said the Alexa had slightly more DR than MX, but with HDR MX blew it away (they provided grabs of the charts).... RED isn't afraid of the tests, they just want them done correctly and in a relevant honest test.
I think the ZACUTO test has failed on the fact they let each camera "pro" relight the scene...This alone discredits the 'test." If they wanted to do it right, they could have lit the set with a greater DR than any of the camera's can physically capture and see which ones actually capture the widest range of DR, maintain resolution in the harsh contrast, as well as color rendition... This is a scenario where RAW and LOG would prove invaluable...
