the sunday and monday run downs are a proven system for pulling 4 dights.go back any year. and they will produce on time ,1week later,up to four weeks later. thats why i find four dights back in 2006,week by week. you could go back to 1998 and it will still produce for 2007.bud1 do the math,put your own research into it. and you will become a fan in this workout as i am.bud1
