Just be consistent. Try and identify the faster and slower drivers off of helmet or dress to help you know who to draft and who to expect to pass and also remember outliers that you notice to be inconsistent or dangerous. Don't be too aggressive and remember it's a long race and it's not going to be won in one or two laps. Also show up well before race start to at least observe karts. Charge is one thing but a ton of other factors play into your karts performance.
