My suggestion would be to find one task that you can do really well and focus on making that a reliable and consistent capability. This all goes back to your strategy...defense? Score high? Score Low? Whatever it is, consistency is hard to come by in these competitions and it is usually better to do easy and simple tasks well and consistently rather than doing hard tasks inconsistently. Teams would usually rather pick a team that can score low 90% of the time quickly than a team who scores high 30% of the time and takes an eternity to do so.
