How about fitting a regression with a quadractic term plus a group*quadractic term along with the usual group and linear trend terms?

Subject: studying different rates of deceleration
What would be the best way to study different rates of deceleration? For example, group A has means for five repeated measurements: 20, 12, 8, 6, 5 And group B has means: 24, 20, 18, 17, 16 Both groups show a decelerated curve but group A decelerates at greater rate than group B.
Would computing Area Under Curve capture this difference?
Thanks so much for any suggestions.
