Recall the expected change in 28-day strength is equal to ₁ = 1.2 times the increase in accelerated strength. The expected change in 28-day strength (in pounds per square inch) for a decrease of 80 psi in accelerated strength can be thought of as an increase of -80 psi and therefore is equal to 80 x or 96 X psi.
