I usually watch the first 3 or 4 races a horse runs in each season just to see how it runs, then for the rest 0f the season I just skip by the races without watching.
I have noticed a pattern as to whether or not I watch a race. Almost always when I watch a race my horse does well in the race, usually winning the race, but if I skip through the races without watching my horse very rarely wins.
There are a couple of examples below and these results are very repeatable, they are not just good race performance v's bad race performance.
Both wins below I watched the race and my horses won comfortably, both losses I skipped the race and my horses didn't win.
