Hi,
To get the correct reading for this circuit select Simulate>>Interactive simulation settings, change TMAX from 1e-5 sec to 1e-7 sec, this setting will force the simulation engine to take more sample data and in this case it will give you the right reading. Don't be surprised if you get reading that's not the same as your calculation because the SPICE engine simple guesses at an answer and plugs that value into a matrix, if the answers to all equations in the matrix falls within a tolerance the SPICE engine will accepts that guess as the answer. There are many simulation settings that you can change to make the tolerance smaller but at the end of the day, you are not guarantee the same reading as your calculation.
