Todays selections

I have been reading threads for a while now & am quite impressed with the knowledge shown & helpfull hints given. I hope I can contribute as well.
I have been working on systems like most of you and was wondering if anyone can assess results.
I have 2 systems that i work on if anyone can comment on figures that would be great.
1) Started last month : Results for March 36 races, 23 Wins, 29 places
April 82 races, 26 Wins, 55 places
April is still continuing but is not performing as well

2) I have refined top system as of 19/4/2007
38 Races, 16 wins 32 places
Any analysis would be apporeciated
