We have the Leap Bridge Precast package which is updated to vers 09.00.02.01.
I have found when I have used a 3000 psi Cap/Seat concrete strength the modulus of elasticity, Ec will show the correct value of 3320 ksi, however it has occasionally changed to Ec = 3834.3 ksi with no chnage from the user. This is the Ec for 4000psi f'c.
I have not been able to recreate this on demand, but it has happened several times.
