I'm trying to calculate the N0 for some other plays, and I'm getting strangely low numbers. Checking my calculation against CVCX, I'm getting a number precisely a factor of 100 smaller.

N0 = (SD^2)/(EV^2)

For this example spread: N0(custom) = (359.88^2)/(31.46^2) = 130.86, not 13,087.
What's going on here? Where's the factor of 100 coming from?
