Haven't ordered the DVDs yet, but I plan to next week.
Beanland, I'm not sure what method he's using in the DVDs, but Grunch had a good post on fold equity here:

Also, by estimating that you're a 60% favorite, you don't need FE. You never want villain to fold. You're already +EV, where as FE is added to current equity to make a -EV play a +EV play(having only 40% equity but wanting more than 50% to make your play +EV). I'm no math expert but I'm pretty sure that any calculation will give you a negative number.
Using Grunch's method I came up with 16% (1+1-1-1-1+1= 1/6 which is 16%)
Notice that his method is unusable as a favorite, since (1+1+1+1+1+1-1-1-1-1=0/10 which obv equals zero).
I'm wondering if his math isn't pot+bet+call/(equity-investment)
Now going back to his math, but us being the 2:3 dog:
30/(30*.4)-10
30/12-10
30/2=15
That's close. Not sure if that's what he was saying though.
Consequently 30/(30*.6, or 18)-10=3.75 so you'd want villain to fold 4%. Doesn't make sense to me since we don't want villain to fold, us being the favorite.
I'm probably doing it wrong too. But hopefully the above post I linked to will help.
