This is interesting but have you considered tweaking in it a bit? i.e. take only games with both pitchers struggling in the last 3 or 5 games or one pitcher struggling and both teams hitting the ball very well in the last 3 or 5 games, etc. etc.
Also, I never did get an answer for my previous question:
Do they offer this 1st inning bets in a Vegas casinos or is it just available on a few online books?
the basic principle of this system is not based on trends or supporting stats. It's called the BS System for that very reason. Best thing is to just have faith and trust in it. Don't try to fix something if it's ain't broke.
BOL!! and welcome aboard.
I have never gambled in Vegas so can't answer your second question.
