I disagree that they are meaningless, but you're right that they don't tell the whole story.  Your suggested benchmarks are certainly useful, and I've also just added a suite of 7 macro benchmarks in the latest spate of updates.  Take a look at SystemDictionary>>macroBenchmarks.

Interestingly, a great macro benchmark that leverages off the old standard is...

	ContextPart runSimulated: [0 tinyBencmarks].

It's a trivially simple meta version of tinyBenchmarks, but it shows that, while J3 shows a 3x and 6x improvement in bytecode speed and send speed, its overall gain is currently typically closer to 2x.

(...another fun one is to run tinyBenchmarks in the InterpreterSimulator ;-)
