Another "problem" with Dhrystone which is also present in Dhampstone is that since they are single file programs they are subject to certain optimizations possible for machines with large numbers of registers such as allocating blocks of registers to procedures, and a different block of registers to the procedure it calls. The Stanford MIPS guys are looking at this. But this technique doesn't work too well on large real programs which either recurse or are multiple program files compiled separately and then linked together.
