Ignoring possible references to 240P, the actual game in-person seems to be pretty chaotic. Since scoring rows earns the most points, you should probably just focus on that. Most effective strategy is probably just winning auton and getting the Home Row Bonus, that will probably be killer.
In Live Remote Tournaments, the matches I have watched are relatively calm. So try to put 4 balls in a couple of goals, but make sure that you have ALL THE BALLS SCORED! THEY ARE ALL WORTH POINTS! And always be touching a goal at the end, even if it isn’t the best goal to be touching.
Well is a subjective word. Depends on your definition of satisfactory how much driver practice will be necessary.
If satisfactory is “We had a good learning experience and won a couple matches”, then about 2 hours of driving practice would probably get a little past there. If satisfactory is “We did the Vex hat trick, winning the Tournament, Robot Skills, and Excellence award”, then maybe upwards of 12 hours of driving practice would be closer to your expectations.
Skills practice always helps with your literal skills, with the added bonus of helping with your skills score. Doing drills is nice too. Maybe you could practice going up to a goal and putting a ball in it, fielding, cycling, etc.
