I am a Sports better of many years. I handicap tennis and baseball and buy selections on NFL. Have failed miserably at ice hockey, NBA and NRL. (why do they keep changing the friggin rules and teams in NRL???)

Anyway my results overall seem to be about the same each year +5% on each. I am great believer in betting the same amount on each game throughout the season as you never know when the good runs and bad runs will come. The 2% per game rule is a good one in my opinion.

One thing I have noticed is that when I get ahead about 12-15% on NFL and MLB, bad things happen. I now cut my bets to 1% or even .5% when I get 12.5% ahead and then go back to 2% when the overall figures get back to normal. You might say that if you get a big winning streak you are minimizing your profit. I agree but in my experience the winning streak has got me to the +12.5% and more often than not the percentages go back to normal at about this point.

The one thing not to do is bet more when you are losing. While not maximizing profits on a huge winning streak is a blow to your ego, doubling and redoubling on huge losing streaks is a blow to your bank and the rest of your life. In my opinion any progressive betting method on sports is doomed to failure unless you have a great method of backing outsiders.

I bet the same on my tennis bets no matter what because I bet short price favs and often go on 20 -25 winning streaks.

The hardest thing about sports betting is getting to the point where you can bet the same amount every year. We start out at $1000 bank betting $20 and win 10% (100) the first year. The next year you think this is great and double up and win $200. The following year you do the same and double again, but a bit of bad luck and you lose 8% (320).

So overall in three years you have done pretty well (+10, +10, -8) = +12 but you have lost money and are back to square one.

Sports bettng is a cruel hobby at times A bookmaker/punting friend of mine once said to me, a punter can have some miserable days but once in awhile all your bets come in and you feel wonderful. This feeling doesn't come to non-punters and at the end of your life you will have been grateful for having had that experience.

Hope this helps.
