My advice is similar to Wisnu M.. Invest your WTTT winnings each week in upgrades to improve your WTTT time only enough to keep you in Group C/B. If the gap from C to B isn't much then try to move from B to C.

This is an investment in future WTTT but if you are struggling to decide which ones to upgrade then pick the ones that will help you progress in career too. I used this approach when aiming for 100% completion.
