"It's been going well and to be able to kick off Group winner after Stakes winner after Group winner is something I'm quite proud of and quite chuffed with myself," he said.
"I've put in a lot of time and a lot of effort into my craft and that's what I want to do. I want to be the very best of the best and I think putting myself in that position to do so, you can see the results on the track."
Stanley cashed in on Losesomewinmore's affinity with the Flemington straight to sweep to a decisive win.
The Richard and Chantelle Jolly-trained gelding, who started $15, scored by two lengths from well-backed $2.90 favourite De Bergerac, who finished one length clear of Herecomesthestar ($17).
It was the fifth win down the Flemington straight for Losesomewinmore but first over the famous 'straight six' course and Stanley was impressed with the performance even if conceding there were some anxious moments.
"The 1200 metres was the only query, it's the only time he does get beaten down the straight," he said.
"I just knew he does hit that flat spot. There was a lot of speed in the race and I was able to track Harry Coffey (on Fancify) everywhere I needed to go and what I did turn him lose he didn't actually hit that flat spot.
