Parameter Charts and WFO

I read in the manual that for WFO simulations, the parameter chart supposedly displays the average result from the cycles. But I don't understand the chart included below. It says "30 Cycles average: 3.07", which doesn't match with what the actual chart shows. The chart shows a strong maximum at 0. Does the actual chart only display the final cycle results or something?

My interpretation: the parameter has no effect on performance except for the 0. But the 0 is not selected because Ascent looks for plateaus, not for single peaks.

I think that the parameter gets a more or less random value at any cycle and their average just happens to be 3.07. I would not optimize this parameter, but leave it at 0.
