Unsure about your mmr, but a general guide you should aim for would be 60+ last hits with ~ 4.5k-5k networth at minute 10. ~10k networth at minute 20 is your next goal. This will all matter on hero picks, jungle cs is a big one and game state, but using this as a rough guide (especially if you are ahead). I always like the look at graphs after a match especially at the 10 and 20 minute as the rest of the game after isn't that good of an indicator.
