You got this! You can rebalance if it isn't working. And this is an experiment. Plan for things to not be perfect. That is how you learn for a bigger ride later.
I don't start doing this until I've made an error. Often a third of the board is no longer on my radar at that point. So I will rarely compete on bonus words. I'm usually in the top 15-20% on accuracy, though, when I'm not perfect.
