Curious...

I've always had my cars weighed at the local dump. You drive in, weigh the car, dump your crap, drive out, weigh again and they calculate the difference and charge you. Mine let me just drive in, weigh the car and leave, and from my own experience, they are pretty accurate. Same type as you find at the track.

I was wondering, now that i'm aware ov my awful weight bias and trying to fix it, would just driving the front wheels onto the scale, getting a reading, then backing the rear wheels (in the same place) and getting a reading work for accurately measuring bias? I'm sure if there was no traffic my scales would let me do that. If i were to get as much ov the car onto the scale (wheels closest to the middle) as possible... then repeat on the rear, would that be worth anything? Perhaps not to accurately add up to a whole, but maybe just to ballpark my bias? I'm pretty sure my scale wouldn't even charge me to do that.... i'd just get the usual funny looks...
