You average 5.5 CS per minute as Mid; Platinum players average about 6.3. 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 deal 15% of your team's damage to champions as Mid. Carries should be closer to 25%. Stay alive in fights by attacking whatever is closest instead of diving for the backline, and finish damage items before defensive ones.
You take part in 29% of your team's kills; Platinum players average 55%. After your first item, look to rotate for dragon, grubs and herald, and keep Teleport for fights rather than for farming.
You spend 10% of your games dead. Late deaths cost a minute each; when a fight is lost, back off and defend rather than adding one more death to it.
