We should all remember,unless grossly in error, the scales at the event are
THE SCALES, period.
Since all things have "tolerances' (euphemism for errors), its to be
expected with scales. A good way to "hedge' against scale variances is to,
if possible, weigh the car on the event scales BEFORE running. At a weekend
event, where things aren't always set up early enough, and there's lots of
other things for all of us to do it may not be possible to always do that.
However, at Nationals, its smart to get a scale "baseline" ahead of time
then, make sure there's a 10+# cushion to cope with whatever, including
possible wind influences, after accounting for fluid losses.
