Parlays, Reverses etc

[Zybomb]

Penguin (and others if you agree or disagree) I was wondering why you felt parlays were wasting money. Here's how I see it

3 team parlay: On average roughly 6:1

So comparing it to betting individual games.

If you go:

3-0 $600 (+$300)
2-1 $-100 (-$200 )
1-2 $-100 ( Break even )
0-3 $-100 (+$200)

A 2 team parlay 3:1

2-0 $300 (+$200)
1-1 $-100 (-$100)
0-2 $-100 (+$100)

Assuming on an EV stand, wouldnt this make sense?

Also what are peoples opinions on reverses?
