CP curve goes up for longer time periods

[Steve Mansfield]

Hello

Not sure if this has been asked before, and it could well be operator error, so apologies if thats the case.

When I check the CP curve, it mostly gown down and right, however it also goes up and right.

Here's a screen shot - am I doing something wrong?

TIA!

At or near to Pmax it sometimes does that.

I don't know why.

That's possible, let's take a look at following example:

10s at 1000W followed by 10s at 200W and another 10s at 1000W; Your best 20s average power = 600W, your best 30s average power = 733W

Curve goes up in that case between 20 and 30s!

Ahhh - makes sense - thanks!
