I’ve found they're much easier for most people to use. It's much<br />

easier to think about 25% of a number instead of 22% of a<br />

number. When you’re a couple percentages off in your final<br />

answer, it’s not a huge deal for a couple reasons. First, a close<br />

decision is a close decision. In terms of EV, it’s not a large<br />

amount one way or the other. For example, let's say you needed<br />

45% equity to make a call. You estimated your equity and came<br />

up with 47%, so you called. Later you realized the more<br />

accurate answer given your assumptions was 44%, and you<br />

would have folded. If you were to calculate the EV for those<br />

numbers, you'd find out the results are very close to one another<br />

and matter little.<br />

The second reason estimates are ok is because you’re working<br />

with a guess on his range and are probably off at least a hand or<br />

two. This doesn't mean we get ridiculously sloppy, but we are<br />

working with an educated guess in real time.<br />

As you get practice examining these situations, you'll soon<br />

become very proficient estimating your equity against an<br />

assumed range, almost as if it were second nature.<br />
