the nub of the problem is not on the benchmarks. There is something
to be said for the good old daays when you looked up the instruction

that speed is that timing is a black art.
Those good old days never existed. Those manuals never accounted for
things that affected timing even then, like memory latency or refresh
time.
Well, as Gilbert and Sullivan wrote:

- No, never!
- What, "Never"?
- Well, hardly ever.
Look up the LGP-30. It was quite predictable. It has been a while.
