W= Cloth Weight before Drying (in lb.) T =TimedDry Setting (in 5-minute increment)
W T

Since the dryer balls are irrelevant, David's experiment data makes it possible to derive a useful guide timedDry setting! This made me recall the first psychological undergraduate experiment when repeated some random trial over and over not unlike what David did. Great job, David. Hat off to a wise and encouraging father!

One question for David: Did you weigh the wet clothes after washer had spinned your cloth load?

***** details ********
proc reg data=DryerBalls; * plots=all;

model Time = WeightLB ;
run;

data LookUp;
do cloth = 5 to 60;
timedDrySetAt = round((14.90749+
1.58846 * cloth), 5); ** WeightLB=Weight * 0.00220462;;
output;
end;
run;

An inspection of the original plots may suggest a regression only with heavier loads, But such regression made no difference in the final look-up table,
