I agree about that alachesu but the charts are quite misleading then... it shows it giving double the flow of the other tops.. now the other tops are going to have that flow all throughout the loop.

3.47 will never happen throughout the loop, just at the exit and then immediately split it in half (ie. performance through the loop will be exact same as all other tops)

Except now you're using the warm loop to heat up the cold loop..

so.. what am I missing here? I don't see the point
