radiators have no influence on speed

maybe i read it wrong....there are two different graphs which show the speed per rads setting.
however both show a straight decreasing line with the same angle...so the difference remains the same.
the lower line shows a speed of 555kph with 50mm opened rads, and only 505kph with 310mm opened rads(which is not fully open).

50kph difference between not fully closed and not fully opened rads...

As noted, hard to read the graph, but assuming 'speed' is on the bottom (x axis) and that it goes as follows

520 - 530 - 540 - 550 - 560

Now looking at the point where the two curves intersect (y=0) the bottom (x axis) we have

1st @ ~523.5kph
2nd @ ~528.5kph

5 = 528.5 - 523.5

That is what I got, but again, I could be reading it wrong too.. That graph is hard to read

But..

Lets not use that graph.. Lets use the 109E data your claim was based on! That would be the correct thing to do! Now that I got your att on the subject!
