Summation based benchmark for calculators

On the HP-50G, I entered the formula into the Equation writer, popped it to the stack and hit EVAL. I get about 28.2" in exact mode and about 25.5" in Approx mode, giving a result of 1395.3462877 in both cases. I'm assuming that's the way I'm meant to do it? I also duplicated these results using ->NUM just to check, but got roughly the same measurements. EVAL in the equation editor also got a similar result to using EVAL on the stack entry.

It's interesting that my fx-9750gII (upgraded with 9860gII OS 2.04) beats out the 50G. My fx-9750gII gets about 22" for sum(1,1000) giving me 1395.346288 as a result. Then I tried it out on the fx-9750g+ (earlier generation) and got 1' 39.5". Just for laughs, I "souped up" the 9750gII with the FTune application (speeds up the CPU and bus clock) and got four seconds for 1,1000. Wow. I wonder what I'd get if I'd newRPL'd the 50G?

BrickEdit: added gII to last instance of 9750, as it wasn't clear which machine I souped up. Could be a laugh trying to "soup up" the G+.
