@langeo To each their own. I'm not endorsing parlays. but if your handicap determines if one outcome is going to happen another is more likely and your book allows you to make the bet parlays are absolutely profitable.
If A is 52.4% likely to happen I break even. If when A happens B is 55% likely to happen doing a parlay is ABSOLUTLY profitable. Anybody with eyes can see if the Titans win the game it will be with ball control and keeping the ball away from the chiefs. If I pick the Titans +7.5 why wouldn't I pick under to get +264.
I also am in the process of tracking all my two team parlays since Dec 1st. Undoubtedly I have had large swings and lost quite a few. But as I said in another post. My overall picks have been under 52.4% but I am up now 33.7 units. (On original post I was only up 20 some) I have missed a lot of first legs and the parlay dies, also in an attempt to find parlays I deem correlated quite often I have missed both legs of the parlay but who cares right. I am picking over 60% on the second leg of parlays which have been quite profitable.
In theory could those numbers reverse and create heavy losses, ABSOLUTLY. but if your searching for items that are correlated it certainly increases your chances. I'm not out here waving the flag for always parlaying items, but I think any time in the gambling world when your dismissive of something your missing an opportunity.
I personally hate making bets off of trends and stats. But I make sure to follow all the people in here that use "analytics" or trends to make bets to try to learn and combine what I do with what they do.
