You average 4.3 CS per minute as ADC; Gold players average about 5.8. Every 15 CS is roughly a kill worth of gold. Practise last-hitting under tower, shove the wave before recalling, and catch side waves between fights instead of standing in lane doing nothing.
You take part in 33% of your team's kills; Gold players average 53%. After your first item, look to rotate for dragon, grubs and herald, and keep Teleport for fights rather than for farming.
You place 0.5 control wards per game. Just one per recall denies the enemy jungler information about you and makes objective fights far safer.
Your main role is only 50% of your games. Each role has different macro; playing one primary and one secondary role gets you a lot more repetitions of the same decisions.
