What's a reasonable length for a stomp?

Had a game that ended 45 minute long 65-20 in kills where I got my position 1 sniper a couple early kills on the enemy position 5 and past the 10 minute mark I was permanently warding the enemy jungle and pinging to engage on anyone out of position but the kills didn't really transition into towers taken.

I was trying to push side waves that were getting ignored as much as a support with bad wave clear can but I'm unsure how much I could have accelerated the game on my own or if it was more on my cores for not hitting turrets.
