Question on pace

[albatross]

Hey guys have had a lot of loser that ran on lead slr then race or same as race pace previous won at.Which i hate in previous race's showed fighting win
today up trk.With mdn winner i can understand or excuse as a class issue.
But this happen weather last race now understand farther back you go is little more suspect.?But all thing being equal and stops when only has to run as before some time you losea fight some you win can deal with that one's hate most get easy open lead get a slr fraction and still choke.Understand they all have the class dist ability as before.No big change in class or dist they all proven thier ability.What could be problem maybe just bad streak going threw then agian maybe not could be somethig not takeing in account.
Any suggestion welcome
