So your telling me the weight would stay the same on 1 corner if you reduced the pressure in that tyre.
Also i dont know what scales you use but setting a car up in its race trim i.e pressures, fuel, driver with helmet etc, gets accurate results down to a KG. At least this way your sat in the car on the line knowing you have exactly the same car that was setup. Even the tyres you run (Radial or crossply) have an effect.
I do understand the principle of doing this.
So if you take your 80PSI all round and adjust 1 corner half a turn on suspension to shift the weight you could be over exaggerating the efffect when running the tyre at 25-30PSI race pressure.
Just something i have noticed when setting up single seaters.
everyones got there own way though.

Rubbish!
Corner weighting a full size car with lower pressures will result in the tyres compressing and giving false inaccurate scale readings.
You set a high 'constant' pressure for accuracy,
The wheels and tyres are unsprung weight and do not effect the corner weight forces
you need to understand the principles and reasons for doing this... it's to set 'sprung' weight balance using suspension adjustments and to give values in order to calculate centre of gravity etc
also on a track tyre pressures change with running temperatures and unsprung weight changes as tyres wear.
