Draw at end of any quarter - AFL

With quarter by quarter score punting available, over the last 18 months or so, I've been amazed at how often this comes up. I've had a very good strike rate on punting that there will be a draw at the end of one of the quarters in a match. Looking at Unitab odds, if you put $5 on every match in a round, with the usual return being $10 per $1 unit, if it happened in just one match, there would be a return of 20% on total investment. If it happens twice in a round, then a return of $100 for $40 invested.
Thought I might start, from this round, with two multis per round at $5 per multi on this; one with two games linked to return $500 per $5, one with three games linked for a $5000 return per $5.
For this round: will take Hawthorn/Sydney into St Kilda/Kangaroos for the 2 game option; then will have Bris/WB into Carl/Pt Adel into Coll/Melb for the 3 game option.
Let's see how it goes!
