He is talking about a concept named "1 minus Alpha".
For example, let's assume we're on the river in a hand.
The opponent bets $100 into a pot of $200.
His bet needs to work 100/(100+200) = 1/3 times in order to break even with his bluffs, or A = 0,33%. If we fold more than 1-A our opponent can profitably bet any two cards. Thus, to keep our opponent indifferent to bluffing, we need to defend (either by calling or raising) 1-A = 2/3 = 0,667% of the time against this bet. 1-A can also be expressed as our "minimum defense frequency". The same logic applies to flop and turn spots as well.
If I was to write a formula for it, it would look something like this:
A = Bet size / (Bet size + pot size)
Minimum defense frequency = 1 - A
It's quite easy to obtain these frequencies by doing simple math yourself, but for multi-tabling 6 or more tables I could see the benefit of having this function.
