This is a complicated topic and many do not want to expend the energy to fully understand what's going on. This is not a slam on anyone... but there are many nuances that are easily missed, and you have to get your mind fully around the issues.
To your questions ... yes .. if you read the latter half of my long text .. I am openly admitting that I would be willing to compromise "perfect" corner balance.....to instead try to achieve a purposeful front "weight jacking"... where the new target is to get equal front weights.
Why ?.....
Because for most of us... especially for track use....it is really spooky to have "perfect" corner balance ( with unequal LF and RF weights, because the car actual weights are not equal left-to-right)...and then find yourself with really bad thresh-hold braking. One of the front tires will then always lock up first because to get "perfect" corner balance...you "properly" loaded up the two front tires unequally to match where the front masses are located ( i.e...unequally)
Instead...IMHO.... a better "compromise" is to target equal front weights...to gain better threshold braking characteristics....at the expense of less-ideal "corner balance". What usually occurs when you gain equal fronts is that the rears are slightly out of whack ( from a "perfect" corner balance standpoint). This then... makes the car behave slightly differently in left-to right turns...as you so correctly point out....but not THAT much of a difference to make a real difference....if you get things close.
So...there are many therories or "targets" you may strive for...but I like this "equal-front" approach.... and this is the basis for my longish dialogue with Randy Blaylock...avid racer. I was converted to his view, which is this same equal-front theory.
EDIT---> if people like reading up on this stuff, here is a link with further embedded links...be prepared, sit down with a large cup of coffee and a note pad
