Your'e obsessed with posting about lift. Is it because you've got the instrumentation to measure it?
In the realm of economic driving, the destabilizing effects lift are not an issue. Neither is adding downforce.
What we care about here is drag. We do indeed measure it with adding mods, then doing tuft testing, A-B-A testing, coast down tests. Long term gathering of data over the same ground, day after day.
We don't have many million dollar wind tunnels.
In the speed ranges in question, measuring lift is a roundabout way of measuring a component of drag. It is by no means the source of all drag. Not even close.
I suggest you climb down off your well beaten dead high horse and try participating in a civil manner.
You have a great deal to add here. Try adding it and not contesting every other thing you see.
